Hydrolysis of Salts Quiz

An introductory quiz on Hydrolysis

In order for ionic compounds to undergo hydrolysis, the cation or anion should be a strong conjugate acid or strong conjugate base

 
 

NH4+ + H2O ⇌ H3O+ + NH3

For the hydrolysis of ammonium ions shown in the above equation, if you are to write an equilibrium expression will it be

 
 
 
 

Hydrolysis cannot be carried out without ____

 
 
 
 

Negative ions are bases or conjugate bases

 
 

If NH4C2H3O2 is dissolved in water, will the pH increase or decrease for its aqueous solution?

  • Ka for NH4+ is 5.8×10-10.
  • Kb for C2H3O2 is 5.6×10-10
 
 
 
 

Na2SO4 when dissolved will cause a change in pH to the solution

 
 

KC2H3O4 when dissolved in water will increase the pH of the solution.

 
 

The conjugate bases of strong acids are considered to be weak conjugate bases

 
 

The salt of HCl is NaCl

 
 

In order to break starch (C6H10O5)n to form glucose (C6H12O6) units, starch needs to be

 
 
 
 

C2H3O2(aq)+ H2O ⇌ HC2H3O2 + OH

This equation represents the hydrolysis of the acetate ions

 
 

Which among the following is a strong conjugate base?

 
 
 
 

Ammonium chloride NH4Cl when dissolved in water will cause the pH to increase.

 
 

If the hydrogen ion from an acid is replaced by a metal, the compound obtained is called the salt of this acid.
