tuliskan reaksi hidrolisis dan sifat dari a) Mg(CN)2 b) NaCH3COOH c) (NH4)2SO4

a. Mg(CN)2->Mg2+ + 2CN-
Mg2+ + H2O -/->
2CN- + 2H2O <=> 2HCN + 2OH-
Mg(CN)2+2H2O-> Mg2+ +2HCN+ 2OH-
Basa
b. NaCH3COO->Na+ + CH3COO-
Na+ + H2O-/->
CH3COO- + H2O-> CH3COOH + OH-
NaCH3COO+H2O<=>Na+ + CH3COOH + OH-
Basa
c. (NH4)2SO4->2NH4+ + SO4^2-
2NH4+ + 2H2O<=>2NH3+2H3O
SO4^2- + H2O -/->
(NH4)2SO4+2H2O->SO4^2- + 2NH3+2H3O
