What is the ionization equation for acetic acid and what is the ionization equation for sodium aceta

Because acetic acid is an acid, it contains hydrogen ions.

ch3cooh=ch3coo- +h+

We haven't learned yet, we've just learned.

is CH3COONA=CH3COO-+NA+.

Sodium acetate. It is a strong acid and weak alkali salt, and the degree of hydrolysis of acetate ions is weak, so the degree of ionization of sodium acetate is greater than that of sodium acetate, so the order of ion concentration in sodium acetate solution from large to small is: C (Na) > C (ch Coo) > C (OH) > C (H).

It can be weathered in the air and is flammable. Soluble in water and slightly soluble in ethanol.

Insoluble in ether. 123 when losing crystal water. However, usually the wet method has a taste of acetic acid. Hydrolysis occurs in water.

Sodium acetate is a very weak base (pkb = in aqueous solution, which cannot be accurately titrated with strong acids in water, so non-aqueous titration is required. Choose an appropriate solvent such as glacial acetic acid.

It can greatly improve the alkalinity of sodium acetate.

In organic synthesis, for example, with anhydrous sodium acetate and soda lime.

Eutectic preparation of methane.

, the anhydrous vinegar used should be prepared before use. Place an appropriate amount of sodium acetate trihydrate in a porcelain evaporation dish.

, when heated to about 58 under the key stirring of the glass rod, sodium acetate trihydrate is dissolved in crystal water, and the water gradually evaporates to obtain a white solid, and the temperature is about 120 at this time.

The ionization equation of sodium acetate: ch3coona = ch3coo-+na+, acetate is a weak acid ion, which can be hydrolyzed.

Simply put, acetic acid ionizes in water to form acetate ions and hydrogen ions.

Since acetic acid is a weak electrolyte, complete ionization does not occur.

Corresponding ion equation:

ch3cooh ch3coo +h+ to a reversible symbol.

The ionization degree of most weak acids is about 1%, and the ionization degree is the number of molecules that have been ionized divided by the total number of molecules before ionization, assuming that the ionization degree of acetic acid is 1%, that is, 1000 acetic acid molecules can be ionized in water, and the degree of acetic acid hydrolysis is smaller than that of acetic acid.

Acetic acid is a weak electrolyte, adding water to dilute the acetic acid solution to promote the ionization of acetic acid, and the number of acetate ions and hydrogen ions produced by acetic acid ionization increases; Sodium acetate crystals are added to the acetic acid solution, and the acetate ion concentration increases to inhibit the ionization of acetic acid, and the ionization degree of acetic acid decreases, and at the same time, the acetate ion concentration increases, but the pH increases.

It is related to the concentration of acetic acid, and the ionization degree of acetic acid at different concentrations must be different.

Calculations should be made with the ionization equilibrium constant and the concentration of acetic acid.

The ionization constant of acetic acid at room temperature is ka=

can calculate [h+].
