Homework Answers
HNO2 + KNO2 is acid buffer solution
HNO2(aq) <-------------> H^+ (aq) + NO2^- (aq)
KNO2(aq) ----------> K^+ (aq) + NO2^- (aq)
By adding of strong acid HCl
NO2^- (aq) + HCl ((aq) --------> HNO2(aq) + Cl^-(aq) (aq)
Or
NO2^- (aq) + H^+ --------------> HNO2(aq) Net ionic equation
2.
By adding strong base NaOH
H^+ (aq) + OH^- (aq) -------------> H2O(l) net ionic equation
