Ionic EquilibriumHard

Question

What is the ratio of pH of a solution containing 1 mole of CH3COONa and 1 mole of HCl per litre and the other solution containing 1 mole of CH3COONa and 1 mole of CH3COOH per litre?

Options

A.1: 2
B.2: 1
C.pKa: 2
D.Zero

Solution

1st solution will finally have 1 mole of CH3COOH.

$\therefore P_{1}^{H} = \frac{1}{2}P^{K_{a}}$

and for 2nd solution, $P_{2}^{H} = P^{Ka}$
