What changes do magnesium sulfate put too much in the water

Although we all know that magnesium sulfate heptahydrate has a wide range of functions, and everyone also likes to use magnesium sulfate heptahydrate as a raw material for production, but due to the non-standard reasons of the magnesium sulfate market, many manufacturers will be deceived by the quality of magnesium sulfate heptahydrate when purchasing magnesium sulfate heptahydrate, so in order to help you identify, the experts of Xingtai Magnesium God Chemical Industry will teach you many years of experience, hoping to help you understand. First of all, we can detect from the production process, magnesium sulfate heptahydrate is a crystal form, due to the use of different processes to produce, so the appearance of magnesium sulfate heptahydrate will be different. Generally, the magnesium sulfate heptahydrate produced by the spin-off process method will have more water, so that the magnesium sulfate will form a crystalline form.

If the drying method is used to produce magnesium sulfate heptahydrate, then there will not be too much moisture, so it will take on the shape of powder. Secondly, we can test from the raw materials, according to the raw materials used can judge the quality of the batch, some unscrupulous manufacturers in order to save the cost of production, will generally choose to use waste acid to produce magnesium sulfate heptahydrate. Compared with the original acid, the magnesium sulfate heptahydrate produced by waste acid will be very different in color, and the content of magnesium sulfate heptahydrate will be greatly reduced, and the content of impurities will be greatly increased.

Finally, it is through experimental testing, because the best way is of course to judge its quality through third-party testing.

The reaction between magnesium and dilute sulfuric acid is caused by the formation of bubbles and the heating of the outer wall of the test tube.

Magnesium and dilute sulfuric acid undergo a displacement reaction to form magnesium sulfate.

and hydrogen. The specific reaction process is as follows: before putting in the magnesium strip, there is no obvious change; When the magnesium strips are inserted, a large amount of gas is produced and the outer wall of the test tube heats up.

Magnesium and dilute sulfuric acid react to produce magnesium sulfate and hydrogen, and its chemical equation is: mg+h so = mgso +h, mg+2h+=mg2++h2.

Physicochemical properties of magnesium and dilute sulfuric acid:

1. Magnesium. Magnesium is a silvery-white solid with a metallic luster. Insoluble in water, lye, soluble in acid.

Magnesium has strong reducibility, can react with boiling water to release hydrogen, can produce dazzling white light when burning, magnesium and fluoride, hydrofluoric acid and chromic acid can not react, nor is it attacked by caustic alkali, but it is easily soluble in organic and inorganic acids. Magnesium.

Valency in chemical reactions.

Usually +2 valence.

2. Dilute sulfuric acid.

Dilute sulfuric acid is a colorless and odorless transparent liquid at room temperature, with a density greater than water, and concentrated sulfuric acid is commonly used.

The concentration is 98%. Dilute sulfuric acid makes purple litmus red, because dilute sulfuric acid is acidic, and acid can discolor litmus, colorless phenolphthalein.

No change. Dilute sulfuric acid can react with active metals to form hydrogen gas, and can also be combined with basic oxides.

The reaction produces salt and water.

The above content reference: Encyclopedia - Magnesium.

Encyclopedia - dilute sulfuric acid.

Magnesium reacts violently with dilute sulfuric acid and dilute hydrochloric acid, with a large number of bubbles.

Chemical Equation:

Magnesium and dilute hydrochloric acid reaction: mg + 2HCl = mgCl + h Magnesium and dilute sulfuric acid reaction: mg + h so = mgso + h <

Acids are universal:1) The acid solution can react with the acid-base indicator.

1. Colorless phenolphthalein does not change color.

2. Purple litmus turns red.

2) Acid + Active Metal = Salt + Hydrogen.

3) Acid + Basic Oxide = Salt + Water.

4) Acid + Alkali = Salt + Water.

5) Acid + salt = new salt + new acid.

As long as any of the above laws are satisfied, the general properties of the acid are reflected, which has nothing to do with the ionic equation, but it is necessary to pay attention to the change of the valence state of the acid root, which is related to oxidation and reduction.

Magnesium reacts violently with dilute sulfuric acid, has a large number of bubbles, and is hydrogen.

Reaction type: displacement reaction, redox reaction.

2. Chemical equation for the reaction of dilute sulfuric acid and magnesium:

mg+h2so4=mgso4+h2↑；

mg+2h+=mg2++h2↑。

Reaction of other metal elements with dilute sulfuric acid.

Zinc reacts with dilute sulfuric acid, producing a large number of bubbles (but the reaction is not as violent as magnesium and dilute sulfuric acid).

Iron reacts slowly with dilute sulfuric acid and has a small number of bubbles.

Copper does not react with dilute sulfuric acid, and there is no phenomenon.

The chemical equation for the reaction of iron and zinc with dilute hydrochloric acid respectively:

fe+2hcl=fecl2+h2↑；

zn+2hcl=zncl2+h2↑；

Mineral water is water made from natural water sources or treated water sources as raw materials, and processed through processes such as stabilization, sterilization, descaling and appropriate mineralization. Magnesium sulfate and potassium chloride are added to it, mainly to improve its taste and tonic effect.

First of all, magnesium sulfate can give mineral water a certain bitter taste and increase the taste and flavor of the water, which is why many brands of mineral water will add magnesium sulfate. In addition, magnesium sulfate can also regulate gastrointestinal peristalsis wax slowing, which helps to promote digestion and excretion.

Secondly, potassium chloride is also a commonly used mineral water additive, which can increase the sweetness and saltiness of water, and improve the taste and taste of water. In addition, potassium chloride regulates electrolyte balance in the body and maintains normal neuromuscular and cardiac function.

It should be noted that the type and amount of additives should be mastered, and too much addition may have adverse health effects. Therefore, when buying mineral water, you should choose a regular brand and try to avoid buying mineral water with unknown or unclear additives. In addition, it is recommended that people do not pursue the taste too much and ignore the safety and health of drinking.

In short, magnesium sulfate and potassium chloride are commonly used mineral water additives, which can improve the taste and taste of water, and also have a certain tonic effect when the same round is roaring. However, when drinking mineral water, we should ensure the safety of the water source and the reasonable use of additives, in order to better enjoy the benefits of mineral water. <>

Adding edible potassium chloride and magnesium sulfate to water will not cause harm to the human body, and there is no harm in drinking it for a long time.

It is mainly to replenish the ions needed for human metabolism.

Industrial potassium chloride and magnesium sulfate added to water are absolutely harmful to the human body.

Mineral water ingredients are present in it, and the reason is that, unlike purified water, mineral water needs minerals in it.

However, magnesium sulfate and potassium chloride can be dissolved in water, adding magnesium ions, potassium ions, chloride ions and sulfate ions to the water, which are all necessary mineral elements, but not the more the better!

Magnesium sulfate will prevent the intestines from absorbing water, causing you to have mild diarrhea, and the more you drink, the thirstier you get, and he can sell more water.

Potassium chloride increases your nerve excitability Diuresis There is a risk of hypokalemia when you are dehydrated It can be supplemented appropriately.

Added ingredients for the production of mineral water to increase minerals in the water.

Industrial-grade products are not of sufficient purity or contain trace amounts of other harmful impurities.

There is harm, and now is a great opportunity for all business development There are many factors that ignore the environment and life Just like you said that water and things are minerals Hehe, a trick to deceive people, but medically speaking, it is correct I don't know if you have ever drunk groundwater Do you know what water tastes like more than ten years ago Now? That's good.

Not very well, I may not know, but I do know that medical alcohol can be sterilized, but industry can't, and it can be done.

This is also for the needs of industry.

The purpose of adding potassium chloride and magnesium sulfate to water can be several:

1.Provides nutrients:

Potassium chloride (KCL) and magnesium sulfate (MgSO4) are both nutrients that plants need.

Potassium chloride provides the potassium required by plants, which plays an important role in the growth and development of plants.

Magnesium sulfate provides the magnesium required by plants, which plays an important role in the synthesis of chlorophyll and the photosynthesis of plants.

2.Adjust the hardness of the water:

Potassium chloride and magnesium sulfate can increase the hardness of water, that is, the concentration of metal ions such as calcium and magnesium in water.

The right amount of water hardness is beneficial for the growth of certain aquatic organisms or hydroponic crops.

3.Control the conductivity of water:

The addition of potassium chloride and magnesium sulfate can regulate the conductivity of water.

Conductivity is an indicator of electrolyte concentration in water, which is of great significance for water quality analysis and some experiments.

It is important to note that the addition of potassium chloride and magnesium sulfate to the water must be done in the appropriate range to avoid problems caused by excessive or insufficient amounts. Different applications and needs may have different dosages and ratios.
