Question

What is the overall chemical equation for the reaction of tums, milk of magnesia and baking soda with stomach acid?

Answer 1

neutralization reaction

Answer 2

Explanation:

Stomach has a very strong acid known as hydrochloric acid.

• Tums is a type of antacid with an active ingredient of $CaCO_3$.

Reaction of tums with HCl is given by the equation:

$CaCO_3(s)+2HCl(aq.)\rightarrow CaCl_2(s)+H_2O(l)+CO_2(g)$

• Milk of magnesia is a chemical compound with molecular formula of $Mg(OH)_2$

Reaction of milk of magnesia with HCl is given by the equation:

$Mg(OH)_2(s)+2HCl(aq.)\rightarrow MgCl_2(aq.)+2H_2O(l)$

• Baking soda has a molecular formula of $NaHCO_3$

Reaction of baking soda with HCl is given by the equation:

$NaHCO_3(aq.)+HCl(aq.)\rightarrow NaCl(aq.)+H_2O(l)+CO_2(g)$
