Here are the ionic equations I could handle and I'm pretty sure you will find it helpful :
1) Rolaids : NaAl(OH)2CO3(s) + 3 H+(aq) ---------> 2 H2O(l) + CO2(g)
2) Maalox : Mg(OH)2(s) + 2 H+(aq) --------> 2 H2O(l) + Mg++(aq) [tex]Al(OH)3(s) + 3 H+(aq) ----------\ \textgreater \ 3 H2O(l) + Al^+3(aq) [/tex]
3) Tums : [tex]CO3+ (Aq) + 2 H+ (Aq) =\ \textgreater \ H2O (L) + CO2 (G)[/tex]
