Question

The ionization constant of propanoic acid is 1.32 x 10^-5. Calculate the degree of ionization of the acid in its 0.05 M solution and also its pH. What will be its degree of ionization if the solution is 0.01 M in HCl also.

Answer 1

Calculation of degree of hydrolysis (h):- Sodium nitrite (NaNO₂) is a salt of strong base (NaOH) and weak acid (HNO₂)

Calculation of pH of the solution:-
