(1).Determine the ion that is hydrolyzing water and write the net-ionic reaction.
(A). NaC2H3O2
(B). NH4Cl
(C). ZnCl2

Solution

A)

net ionic equation : Na+ is spectator ion

C2H3O2- (aq) + H2O (l) -------------------> C2H3O2H(aq) + OH-(aq)

B) in this case Cl- is spectator ion

NH4+(aq)   + H2O (l) ------------------------> NH3(aq) + H3O+(aq)

C) in this case Cl- is spectator ion

Zn+2 (aq) +   2H2O (l) --------------------> Zn(OH)2 (s) + 2H+ (aq)
