Answer:
Explanation:
HX(aq) ↔ H+(aq) + X-(aq)
[H+] = [X-]
Ka = [H+] [X-] / [HX]
Ka = [H+] [X-] ÷ [HX] is the acid dissociation constant for an acid at equilibrium.
What is chemical equilibrium?
Chemical equilibrium is the condition in which no net change in the amounts of reactants and products occurs.
HX(aq) ↔ H+(aq) + X-(aq)
[H+] = [X-]
Ka = [H+] [X-] ÷ [HX]
Hence, Ka = [H+] [X-] ÷ [HX] is the acid dissociation constant for acid at equilibrium.
