Regarding the question of chemical hydrolysis, ask a question about hydrolysis

100 ml of CH3COOH solution has a high number of H+s.

It can be seen in this way: 100ml of CH3COOH solution is equivalent to adding 90ml of water to 10ml of 1mol L of CH3COOH solution, and adding water can make the ionization equilibrium of CH3COOH in a positive direction, so the amount of H+ substances increases after adding water, but the concentration of H+ decreases, so the number of H+ in 100ml of CH3COOH solution is more.

It must be more H+ in 100ml of CH3COOH solution, 100 times is much greater than 10 times, which means that there are more CH3COOH molecules, and there are more natural hydrolysis, just like one person doing one thing or ten people doing it, naturally the latter is faster, right.

If it is a strong acid, then both solutions have as much H+. However, CH3COOH (acetic acid, acetic acid) is a weak acid, and the larger the concentration, the smaller the proportion of H+ dissociation; The smaller the concentration, the greater the proportion of H+ dissociation.

Therefore, the amount of CH3COOH (acetic acid, acetic acid) solution with the same amount of substance has a small concentration of H+ and the number of H+.

According to the formula, the thinner the more ionized, so 100ml of CH3COOH solution has more H+.

I really feel a little speechless when I see this question, I'm afraid that the level of the person who makes this kind of question is not enough.

First of all, let me explain your question according to the intent of the questioner.

Fe3+ is hydrolyzed, Fe3+ +3H2O - reversible---Fe(OH)3 (for colloids can not be precipitated) +3H+

The F- of NAF in the solution has: F- +H2O -- ---reversible HF + OH-, which will be hydrolyzed to produce OH-, OH- will be combined with Fe3+ hydrolyzed H+, according to the principle of equilibrium reaction, the product reduction reaction will be carried out in the direction of increasing this substance, simply put, the hydrolysis of Fe3+ will intensify to increase H+ (the hydrolysis of F- will also be intensified), so Fe(Oh)3 will be produced in large quantities, because it is yellow, the color of the solution will be deepened, Because the H+ concentration of the original Fe3+ solution decreases, the pH value increases. This is also the knowledge of double hydrolysis.

But there is a very important issue that is overlooked here, F- can be combined with Fe3+ (commonly known as complexation) to form a colorless complex FeF3, which can be soluble in water, so if your book does not emphasize a small amount of NaF or its solution, then there will be a serious mistake, because the addition of a large amount of F- will make the solution lighter.

Hydrolysis is a chemical unit process that uses water to break down substances to form new substances.

The decomposition of inorganic substances in water is usually a double decomposition process, water molecules are also decomposed, and the hydrolyzed material fragments are combined to form new substances, such as chlorine gas decomposes in water, a chlorine atom and a hydrogen atom decomposed in water combine to form hydrochloric acid, another hydrogen atom and oxygen atom of water molecule combine with another chlorine atom to form hypochlorous acid; Sodium carbonate hydrolysis produces sodium bicarbonate and sodium hydroxide; The hydrolysis of ammonia chloride produces hydrochloric acid and ammonium hydroxide, among others.

The molecules of organic matter are generally relatively large, and hydrolysis requires acids or bases as catalysts, and sometimes bioactive enzymes as catalysts. In acidic aqueous solutions, fats are hydrolyzed into glycerol and fatty acids; Starch will be hydrolyzed into maltose, glucose, etc.; Proteins are hydrolyzed into substances with relatively small molecular weights, such as amino acids.

In an alkaline aqueous solution, fats are broken down into glycerol and solid fatty acid salts, known as soaps, so this hydrolysis is also called "saponification."

1. The acidity of acetic acid is greater than that of carbonic acid, and the acidity of carbonic acid is greater than that of bicarbonate.

2. After the strong acid and strong alkali are diluted by the same multiple as the weak acid and weak alkali, the change of strong acid and strong alkali is the greatest.

3. According to this question, after diluting the same multiple, Na2CO3 solution, CH3Coona solution, NaOH solution, among them, the NaOH solution becomes the most excited, while the acidity of bicarbonate is the smallest, and the acidity is the weakest, so its change is the least (weak acid and weak base are not completely good lead dissociation in aqueous solution, so the weak acid will continue to dissociate after dilution, so the pH change is not large; As for strong acids and strong bases, they are completely dissolved and cautious in aqueous solution, so after dilution, the pH changes the most).

The smallest change in pH is sodium carbonate, because in terms of acidity, the acidity of carbocyphalus is greater than that of acetic acid and greater than that of carbasanoate, so that after hydrolysis, the concentration of hydrogen ions in sodium carbonate changes the least, and the pH change is the least.
