Write the net ionic equation for the equilibrium that is established when ammonium chloride is dissolved in water.
(Use H3O+ instead of H+.)
(Label as acidic, basic, or neutral)
Explanation / Answer
1. Ans :- Ba(NO2)2 on hydrolysis gives a strong base Ba(OH)2 and weak acid HNO2 , therefore the resultant solution must be basic .
Chemical equation is :
Ba(NO2)2 + 2H2O <-------------> Ba(OH)2 + 2HNO2
strong base weak acid
ionic equation is :
Ba2+ + 2NO2- + 2H2O <-------------> Ba2+ + 2OH- + 2HNO2
Net ionic equation is :
2NO2- + 2H2O <-------------> 2HNO2 + 2OH-
2.Ans :- NH4Cl on hydrolysis gives a strong acid HCl and weak base NH4OH , therefore the resultant solution must be acidic .
Chemical equation is :
NH4Cl + H2O -------------> NH4OH + HCl
weak base strong acid
Ionic equation is :
NH4+ + Cl- + H2O -------------> NH4OH + H+ + Cl-
Net ionic equation is :
NH4+ + H2O -------------> NH4OH + H+
