Write the equations of the hydrolysis reaction in molecular and ionic form and indicate how, as a result of hydrolysis, the reaction of the medium (pH) in the solution has a trace of NH4NO3 salts; Cr2 (SO3) 3; CaS. Complete the reaction equations by writing them in molecular and ionic forms: (NH4) 2CO3 + H2SO3 Fe2 (SO4) 3+ (NH4) 2S Pb (OH) 2 + HNO3

The first stage of hydrolysis Molecular equation: (NH4) 2SO4 + H2O ⇄ NH4OH + NH4HSO4 Full ionic equation: 2NH4 + + SO42- + H2O ⇄ NH4OH + NH4 + + H + + SO42- Short ionic equation: NH4 + + H2O ⇄ NH4OH + H + Second stage of hydrolysis equation: NH4HSO4 + H2O ⇄ NH4OH + H2SO4 Complete ionic equation: NH4 + + H + + SO42- + H2O ⇄ NH4OH + 2H + + SO42- Short ionic equation: NH4 + + H2O ⇄ NH4OH + H + as a result of hydrolysis, hydrogen ions (H +) were formed, then the solution will have an acidic environment (pH <7).
