How to remove sediment in water, how to deal with white sediment in boiling water?

If you add vinegar, it will dissolve the scale in the kettle, such boiling water is unhygienic, because the scale is dissolved in the water, you don't want to drink the scale dissolving solution.

When boiling water, don't put anything in the water, let the scale precipitate (solidify) out of the water as much as possible, so that there will be fewer impurities in the boiling water, and it will taste better.

The scale in the pot, remove it afterwards, such as the vinegar you said in the article, I mainly use hydrochloric acid or sulfuric acid at home, mine is a stainless steel kettle, first put more than half a pot of water, and then add 50 ml of concentrated hydrochloric acid or dilute sulfuric acid for the battery, stir well and fill with water, because it is a strong acid without heating, pour it out of the pot after two hours and it will be clean, and then rinse the pot with water.

Don't say that hydrochloric acid and sulfuric acid are toxic, just rinse them with water, and any students or chemistry teachers around you who have gone to high school will agree with me.

Pour out the floating stuff before drinking

The white sediment in boiling water, commonly known as scale, can be removed from boiling water with the following substances:

1. Vinegar scale removal: the main component of scale is calcium carbonate.

And the acetic acid in vinegar.

It reacts with calcium carbonate and is soluble in water.

2. Potato skin scale removal: because potatoes contain a large amount of natural starch, a colloidal solution with great adsorption ability and decontamination ability will be formed when encountering high temperature.

3. Baking soda.

Limescale removal: Because baking soda is weakly alkaline, the main reason why tea scale can be removed is due to swelling, so that the adhesion of limescale decreases, and it is easy to lift off the cup wall.

The method of washing the precipitation is to load the experimental equipment, fold the filter paper in the funnel, place the washing precipitate on the filter paper placed in the funnel, drain it with a glass rod, inject distilled water until it has not been precipitated, and then wait for the liquid to flow away from the bottom of the funnel. Repeat the previous step two to three times, pour the washed precipitate onto the dry filter paper, sweep the remaining precipitate with a glass rod, and absorb the water.

Pellets with low solubility and not easy to form colloids can be washed with distilled water, and crystalline precipitates with high solubility can be washed with dilute precipitant (which can be removed by drying or burning) solution or precipitated saturated solution.

For amorphous precipitates that are easily colloidal, volatile electrolyte dilute solutions should be used for washing. When the solubility of the precipitate does not change much with temperature, it can be washed with a hot solution. The pouring method is used to wash and precipitate, and the washing process follows the principle of a small number of times, and whether it is clean or not can be checked by a special reaction.

Wash the purpose of the sediment

Washing precipitation is to wash away the impurities adsorbed on the surface of the precipitation and the mother liquor mixed in the precipitation, and selecting the appropriate washing solution during washing can reduce the dissolution loss of the precipitation and avoid the formation of colloids. Precipitation is a unit operation in which the target product or major impurities in the solution are precipitated in the form of an amorphous solid phase and then separated.

If the filter residue is the desired substance, the purpose of the scrubbing is to remove soluble impurities from the crystal surface and obtain purer crystals. If the filtrate is the desired substance, the purpose of the washing is to wash out the residue obtained by filtration and to wash out as much of the useful substance as possible such as the target product. However, it is necessary to be careful when washing and precipitating, so as to ensure the accuracy of the data.

The white sediment in boiling water, which is commonly said to carry high scale, can be removed from boiling water with the following substances:

1. Vinegar to remove scale: The main component of scale is calcium carbonate, and the acetic acid in vinegar will react with calcium carbonate and dissolve in water.

2. Descaling of soil sedan late bean skin: Because potatoes contain a large amount of natural starch, a colloidal solution with great adsorption capacity and decontamination ability will be formed when encountering high temperatures.

3. Baking soda to remove scale: Because baking soda is weakly alkaline, the main reason why it can remove tea scale is due to swelling, so that the adhesion of scale decreases, and it is easy to lift off the wall of the cup.

The white precipitate or foam is made up of a precipitate of calcium and magnesium ions in the water.

Solution: The easiest way is to filter out the sediment or foam in the boiling water, but it is more troublesome.

Use a water softener.

Water softening. There are two main ways to do this:

The first is the chemical softening method, which is to add some agents to the water, so as to convert the calcium and magnesium ions in the water into insoluble compounds and precipitate them. For example, soften with lime, but to control the pH value, it is best between 9-10.

Second, adding some vinegar to the water can also achieve the effect of softening, which is to turn calcium into calcium acetate and dissolve it in water.

Tap water has a high hardness and dissolves minerals such as calcium carbonate, and when the temperature rises, the solubility of calcium carbonate decreases and precipitation occurs, and you will also see sediment.
