Given the following information:
(1) Write the net ionic equation for the reaction that occurs when equal volumes of 0.400 M aqueous nitrous acid and sodium hypochlorite are mixed. It is not necessary to include states such as (aq) or (s).
(2) At equilibrium the _________reactantsproducts will be favored.
(3) The pH of the resulting solution will be _________greater thanequal toless than seven.
Explanation / Answer
HClO and NaF
(1) equal volumes of HClO and NaF are mixed
HClO + F- ---> HF + ClO-
(2) at equilibrium, reactants are favoured as HF is stronger acid than HClO
(3) The pH of solution would be greater than seven.

HCN and (C2H5)3N
(1) net ionic equation,
HCN + (C2H5)3N --> CN- + (C2H5)3NH+
(2) at equilibrium, products are favoured as (C2H5)3N is a stronger base than acid HCN
(3) pH of the resulting solution would be greater than seven as CN- is hydrolyzed to give OH- in solution.

HNO2 + HClO
(1) net ionic equation,
HNO2 --> H+ + NO2-
(2) At equilibrium products are favoured as HNO2 more acidic
(3) pH of the solution would be less than seven as HNO2 dissociate to give H+ in solution
