    C6H5O- is the acid group of phenol, HCO3- is the acid hydrochloride of carbonic acid, the weaker the acid, the worse its ability to ionize hydrogen ions, in other words, the stronger the ability to bind hydrogen ions.

    Ask the size of the hydrolysis pH, C6H5O- is stronger than HCO3- to bind hydrogen ions, this hydrogen ion is ionized from H2O, C6H5O- hydrolyzed OH- concentration is higher than HCO3-, alkalinityThere is also [Fe(C6H5O)6]3- is a complex ion formed by the combination of ferric ion Fe3+ and three phenyl groups.

    Complex ions: Complexes are formed by a certain number of ligands (anions or molecules) that are bound around the central ion (or neutral atom) through coordination bonds, and are called complexes. Coordination compounds are referred to as complexes (complexes).

    The ionization constant of HCO3- is less than that of CO32-, that is, it is easy to form HCO3-, and in addition to the fact that the amount of CO2 is not known, it is often an excess of CO2, so that it is correct to form a comparison with D C.

    Relatively strong acids react with relatively weak salts to form salts of stronger acids and weaker acids, but when you get to university, they are a little different, and some of them are special.

    Hydrolysis is a reaction process in which water reacts with another compound, and the brightener is broken down into two parts, to which hydrogen ions are added in the water, and hydroxyl groups are added to the other part, thus obtaining two or more new compounds. In organic chemistry, compounds react with water, and in inorganic chemistry, weak acid or weak base ions react with water.

    The concept of organic chemistry is that water reacts with another compound, and the compound is decomposed into two parts, H+ in water is added to one part, hail bond is added to the other part, and hydroxyl group (-OH) is added to the other part, so that two or more new compounds are obtained. The concept of inorganic chemistry is the reaction of weak acids or weak base ions with water to form weak acids and hydroxide ions (OH-) (or weak bases and hydrogen ions (H+)).

    The most industrially used is the hydrolysis of organic matter, mainly to produce alcohols and phenols. The hydrolysis reaction is the reverse reaction of the neutralization or esterification reaction. The hydrolysis of most organic compounds is difficult to carry out smoothly with water alone.

    Depending on the nature of the hydrolysate, the hydrolysate can be sodium hydroxide aqueous solution, dilute source chaotic acid or concentrated acid, and sometimes potassium hydroxide, calcium hydroxide, sodium bisulfite, etc. This is called alkaline hydrolysis and acid hydrolysis. Hydrolysis can be carried out in batch or continuous mode, with the former often performed in a kettle reactor and the latter mostly using a tower reactor.

    Hydrolysis is a decomposition technique and chemical reaction process. Two or more substances are required, and one of the substances is water, when a chemical reaction occurs, water and the compound will combine with each other, and the compound will be decomposed into two parts, one part reacts with the hydrogen ions in the water, and the other part reacts with the hydroxide ions to decompose the substances into new substances.

    Because water has the dual characteristics of decomposition and fusion, the salt concentration, humidity, acidity and temperature of the whole water and its compounds will directly affect the hydrolysis process.

    The hydrolysis reaction is a water attack and another attack.

    A compound reaction, the compound is decomposed into two parts, the hydrogen atom in the water is added to one part, and the hydroxyl group is added to the other part, so that two or more new compounds are obtained.

    The most industrially used is the hydrolysis of organic matter, mainly to produce alcohols and phenols. The hydrolysis reaction is the reverse reaction of the neutralization or esterification reaction. The hydrolysis of most organic compounds is difficult to carry out smoothly with water alone.

    Hydrolyzed bai is generally a salt.

    dissolved in water, while salt electric du

    The separated anion and cation can be combined with the ionized part of the water to form a new substance, here it can be a separate anion, or a separate cation, or an anion or ion, you don't have to be just stuck in this question, the key is to understand, think about what causes them to hydrolyze in general? It is that such substances as weak acid salts or weak alkali salts can be combined with hydrogen ions or cations in water, and it can also be understood in this way: hydrolysis, as the name suggests, is to decompose water.

    Having said all that, I hope you can understand, and I wish you progress in your studies! Happy every day!

    The ester group is hydrolyzed to generate HCOH and the HCOO is removed below, plus an OH.

    For example, NaCl is hydrolyzed to neutral.

    h2o=h+ +oh-

    Na2CO3 is hydrolyzed into alkaline.

    co32- +h2o= h2co3 +oh-

    It is "the weaker the more hydrolyzed, who is stronger and whose nature is revealed". Generally, there are no reaction characteristics, but there are also obvious, such as weak acid and weak alkali salts will be strongly hydrolyzed when they encounter water, resulting in precipitation, which is generally double hydrolysis, for example, Al3+, Fe3+, NH4+, CO32-, HCO3-, S2-, SiO32-, AlO2-, etc.

    Hydrolysis of organic matter, such as ethyl bromide, reacts with water to produce ethanol and hydrogen bromide, -oh, -br interchangeable; This reaction seems to be characteristic;

    Esters are also hydrolyzed, which is possible in the case of strong acids or bases. For example, ethyl acetate and water are used to produce acetic acid and alcohol at H+ or OH-, but they are heated in a water bath. This reaction is reversible and reversible with esterification.

    Reaction characteristics, the fragrance of ethyl acetate disappears after the reaction.

    Of course, starch can also be hydrolyzed, but it is also necessary to add acid catalysis, when doing starch hydrolysis experiments, add iodine solution, if the blue color disappears, it means that starch hydrolysis. The hydrolysis of oils and fats requires the presence of acid or alkali or high-temperature water vapor, and the industry uses the principle of hydrolysis of oils and fats under acidic conditions to prepare higher fatty acids and glycerol, and uses sodium stearate (the active ingredient of soap) and glycerol to be produced under alkaline conditions.

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. >>>More
