Answer 2

Equation for Hydrolysis of Sodium Acetate (CH3COONa):

The equation for the hydrolysis of sodium acetate (CH3COONa) can be represented as follows:

CH3COONa + H2O → CH3COOH + NaOH

In this reaction, sodium acetate reacts with water to form acetic acid (CH3COOH) and sodium hydroxide (NaOH) [[1]].

Equation for Hydrolysis of Barium Nitrate (Ba(NO2)2):

The equation for the hydrolysis of barium nitrate (Ba(NO2)2) can be represented as follows:

Ba(NO2)2 + 2H2O → Ba(OH)2 + 2HNO2

In this reaction, barium nitrate reacts with water to form barium hydroxide (Ba(OH)2) and nitrous acid (HNO2) [[2]].

Equation for Hydrolysis of Lithium Carbonate (Li2CO3):

The equation for the hydrolysis of lithium carbonate (Li2CO3) can be represented as follows:

Li2CO3 + H2O → LiOH + H2CO3

In this reaction, lithium carbonate reacts with water to form lithium hydroxide (LiOH) and carbonic acid (H2CO3) [[3]].

Equation for Hydrolysis of Calcium Nitrate (Ca(NO2)2):

The equation for the hydrolysis of calcium nitrate (Ca(NO2)2) can be represented as follows:

Ca(NO2)2 + 2H2O → Ca(OH)2 + 2HNO2

In this reaction, calcium nitrate reacts with water to form calcium hydroxide (Ca(OH)2) and nitrous acid (HNO2) [[4]].

Please note that these equations represent the hydrolysis reactions of the given substances. Hydrolysis is a chemical reaction in which a compound reacts with water to form new compounds.
