Acids and Bases - Weak Acid Ionization Constants

Question 1

weak acids

Answer 1

• reach an equilibrium
• ionization equation
  HA(aq) + H2O(l) ->

Question 2

Keq[H2O] = [H+][A-] / [HA] = Ka

Answer 2

• Ka is the ionization constant

Question 3

HCN(aq) + H2O(l) ->

Answer 3

• ionization equation for hydrocyanic acid
• acid ionization constant expression
• Ka = [H3O+] [CN-] / [HCN] = 6.2 *10^-10
