Complete the following acid-base reaction with balanced molecular, total ionic and net ionic equations: calcium hydroxide (aq) + acetic acid (aq) ----> ? I know that calcium hydroxide is ca(OH)2 and that acetic acid is CH3COOH. I also know that one of the products in an acid-base rxn must be H2O. Need help with the rest!

  The formula equation is: Ca(OH)2 + 2HC2H3O2 --> Ca(HC2H3O2)2 + 2H2O HC2H3O2 and H2O are molecular substances and you do not break them up into ions. The ionic reaction is: Ca^+2(aq) + 2OH^-(aq) + 2HC2H3O2 --> Ca^+2(aq) + 2C2H3O2^-(aq) + 2 H2O Cancelling out the "spectator" (unchanged) ions, we get: 2OH^-(aq) + 2HC2H3O2 --> 2C2H3O2^-(aq) + 2 H2O Dividing all coefficients by 2, we get: OH^-(aq) + HC2H3O2 --> C2H3O2^-(aq) + H2O We now have the net ionic equation.
