Weak Acids and Bases (Leaving Cert Chemistry): Quizzes

It partially dissociates into ions

An equilibrium state

The weak acid has a higher pH

Ethanoic acid

Ammonia

$CH_3COOH \rightleftharpoons H^+ + CH_3COO^-$

$[H^+] = \sqrt{K_a × M_a}$

The acid dissociation constant

$[OH^-] = \sqrt{K_b × M_b}$

pH + pOH = 14

17 g/mol
