Identify the correct equation for the equilibrium constant Ka for the weak acid dissociation of acetic acid. HC2H3O2(aq) + H2O(l) ⇌ H3O+(aq) + C2H3O2-(aq)
Select one:
Ka = [HC2H3O2]/[H3O+][C2H3O2-]
Ka = [HC2H3O2][H2O]/[H3O+][C2H3O2-]
Ka = [H3O+][C2H3O2-]/[HC2H3O2]
Ka = [H3O+][C2H3O2-]/[HC2H3O2][H2O]
