Which is stronger to dissolve, citric acid or table salt?

Good afternoon, sodium chloride is completely ionized in aqueous solution, so the solubility is the largest, citric acid because the molecular structure contains a long carbon chain, it is a strong organic acid, and it can only be partially ionized in aqueous solution, and the solubility is relatively small. Citric acid, adipic acid and tartaric acid are similar, and the solubility in water is greatly affected by temperature.

Every day there are all kinds of things that need to be cleaned in the home, so what are some ways to clean and save money? Today, we will share with you 3 affordable and cost-saving cleaning methods at home, as long as you have lemons.

1. Deep cleaning of cutting boards.

Operation: Sprinkle salt on a cutting board, cut the lemon in half, take half and wipe the cutting board with the pulp in a circular motion.

While wiping, gently squeeze out the juice to ensure an even coverage of the cutting board. Let the lemon juice and salt sit on the cutting board for 5 minutes, and repeat the remaining half of the lemon again in circular motions. Rinse the stains off the cutting board with clean water.

Principle: Citric acid is more acidic than ordinary food and can play a role in dissolving stains. Salt and lemon juice are sterilizing, and lemon essential oil makes cutting boards smell fresh.

2. The electric kettle removes scale.

Operation: Mix lemon juice (30ml) with 2 cups of water and pour it into an electric kettle.

Press the heat switch to a natural boil, pour out the boiling lemonade, rinse the kettle with clean water a few times, and the limescale will disappear completely.

Principle: The chemical composition of scale is calcium carbonate, and the chemical composition of rust is iron oxide, and these two alkaline substances will undergo a chemical reaction when they encounter citric acid, and they will naturally become soft and melt.

3. Remove limescale from the glass of the shower room.

Operation: Pour 45ml of lemon juice and 240ml of water into a watering can, shake well and spray on the glass surface, then wipe dry with a dry rag.

Principle: The acidic liquid of lemon can dissolve the oil stain on the glass or mirror, clean the dust, if the glass scale is thicker, then in addition to the scale of the shower room glass use Aozhuli, it is rich in lemon active ingredients, the ability to remove scale is stronger.

Through the above introduction, I believe you must have a new understanding of the cleaning effect of lemon, next time if you don't know which brand of cleaning disinfectant is good, you can try the lemon cleaning method.

Hello friends, citric acid and salt are more soluble than salt, and some scientists have done experiments and the final results show that the solubility of salt is much greater than that of citric acid.

Pro, if you say which solubility is stronger, it must be citric acid, because citric acid itself is acidic, acidic substance, he just has a good soluble table salt, it is alkaline, alkaline is indeed worse than acidic.

It is an important organic acid, also known as citric acid, with the molecular formula C6H8O7, colorless crystals, often containing a molecule of crystal water, odorless, with a strong sour taste, and easily soluble in water. Its calcium salt is more soluble in cold water than in hot water, and this property is often used to identify and isolate citric acid. Anhydrous citric acid can be obtained by controlling the appropriate temperature during crystallization.

It has a very many uses in industry, food industry, cosmetics industry, etc. [1]

Brief introduction. Citric acid, also known as citric acid, has a chemical name of 2-hydroxypropane-1,2,3-tricarboxylic acid. According to its water content, it is divided into citric acid monohydrate and citric acid anhydrous.

Physicochemical properties. At room temperature, citric acid is a colorless translucent crystal or white granule or white crystalline powder, odorless, tastefully acidic [2], and it can exist in the form of anhydrate or monohydrate: when citric acid crystallizes from hot water, it produces anhydrate; Crystallization in cold water produces monohydrate.

When heated to 78, monohydrate will decompose to produce anhydrate. At 15 hours, citric acid is also soluble in absolute ethanol. [3]

Citric acid. The simple structure is shown in the figure, density, melting point 153 (water loss), and decomposition above 175 releases water and carbon dioxide. Citric acid is easily soluble in water and ethanol, the solubility (w w) is 59% at 20, and the pH of its 2% aqueous solution is.

The crystalline form of citric acid varies according to different crystallization conditions, it is slightly weathered in dry air and hygroscopic in humid air, and can be decomposed into a variety of products when heated, and can react with acids, alkalis, glycerol, etc. [3]

Structurally, citric acid is a tricarboxylic acid compound and therefore has similar physical and chemical properties to other carboxylic acids. Citric acid is a strong organic acid with 3 H+ that can be ionized. [4]

Summary. Dear, I am your mentor Mr. Xiao Zhang, I am happy to answer for you, lemon and salt can be anti-inflammatory, antiviral, anti-cold, because salted lemonade has better anti-inflammatory and antiviral abilities than ordinary lemonade, which can inhibit the activity of influenza viruses and prevent influenza viruses from damaging human cells. You can drink more salted lemon water to prevent colds, and people who have just started to catch a cold can drink more salted lemon water to prevent the cold from getting worse and quickly relieve discomfort<>

Why should lemon be eaten with salt.

Cronies split relatives, I am your mentor Xiao Zhang, I am happy to answer for you, lemon and salt can be eaten together can be anti-inflammatory, antiviral, anti-cold, because salty lemon slippery closed water has better anti-inflammatory, antiviral ability than ordinary lemonade, can inhibit the activity of the influenza virus, prevent the influenza virus damage to human cells. You can drink more salted lemon water to prevent colds, and people who have just started a cold can drink more salted lemon water to prevent the aggravation of colds and quickly relieve discomfort<>

Kiss, lemonade also has the effect of **, when you drink lemonade, you can also put a small amount of edible salt to **Oh. It can accelerate the consumption of calories, inhibit the absorption of caloric acid, and promote the decomposition of excess fat in the human body, so that it can be metabolized in vitro. It is recommended that patients with gastrointestinal diseases and kidney diseases should not drink too much to avoid adverse consequences<>

The lemon itself is a fruit with extremely high nutritional and medicinal properties. Lemons are rich in citric acid and are known as the "citric acid storehouse". In addition to sugar, the main nutrients in lemons include calcium, phosphorus, iron, vitamin B1, vitamin B2, vitamin C and niacin.

1. Gargling with lemon water and salt can sterilize, ** oral swelling and pain 2, lemon water and salt to cure colds.

Be sure to run with warm water, the temperature is very low warm water, remember in the impression that vitamin C will lose its effect when it encounters hot water above 60 degrees. It is worth noting that lemon water should be drunk in moderation and should not exceed 1000 ml per day. In addition, lemon water should not be consumed by people with hyperacidity and stomach ulcers due to the low pH of lemons.
