Does this mean no one is able to or no one has had a chance to answer it?
I'll try to get you started on two or three of these but no one here will do all of them for you.
NH4Br. The NH4^+ is hydrolyzed, the Br is not. (NH4Br is the salt of a weak base and a strong acid; therefore, the weak base part[i.e., the NH4] is hydrolyzed.
NH4^+ + H2O ==> NH3 + H3O^+
NaC2H3O2(sodium acetate) is the salt of a strong base and weak acid; therefore, the weak acid part (C2H3O2^-) is hydrolyzed but the strong base part (Na^+) is not.
C2H3O2^- + HOH ==> HC2H3O2 + OH^-
NaBr (sodium bromide) is the salt of a strong base (NaOH) and a strong acid (HBr); therefore, neither Na^+ nor Br^- is hydolyzed.
