Question

Which of the following ions will react with water in a hydrolysis reaction?Cu2+K+Ba2+Zn2+F-SO32-Cl-

Answer 1

Answer;

Cu2+, Zn2+, F-, and  SO3^2-

Explanation;

• Hydrolysis is a reaction of a substance or a compound with water.
• Anions such as Cl- and cations such as K+ and Ba2+ of strong acids and bases to not hydrolyze.
• For example; KOH and Ba(OH)2 are strong bases, and HCl is a strong acid.
• All the other ions will have a hydrolysis reaction with water and establish an equilibrium;

Cu2+ + HOH ↔ CuOH^+ + H+  

Zn2+ + HOH ↔ZnOH^+ + H+  

F- + HOH ↔ HF + OH-  

SO3^2- + HOH ↔ HSO3^- + OH-
