Al(H2O)6^3+ H2O ==> Al(H2O)5(OH)^2+ + H3O^+

CO3^2- + HOH ==> HCO3^- + OH^-

NH4Ac + HOH ==> NH4OH + HAc
(NOTE:) Actually NH4OH doesn't exist; it is NH3 + H2O but I thought it easier to explain what is going on. When I was in school NH4OH was a compound; it has been shown not to exist and the above equation would have been the acceptable answer 40 years or so ago.
