Question

Every antacid contains one or more ingredients capable of reacting with excess stomach acid (HCl). The essential neutralization products are CO2 and/or H2O. Write net ionic equations to represent the neutralizing action of the following popular antacids:

-rolaids
-maalox
-tums
-Milk of magnesia

Answer 1

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)
`Al(OH)3(s) + 3 H+(aq) ----------\ \textgreater \ 3 H2O(l) + Al^+3(aq)`
3) Tums :
`CO3+ (Aq) + 2 H+ (Aq) =\ \textgreater \ H2O (L) + CO2 (G)`
