# Excess hydrochloric acid in your stomach can be neutralized by magnesium hydroxide, which forms magnesium chloride and what?

Apr 11, 2017

$\text{2HCl + Mg(OH)"_2}$$\rightarrow$$\text{MgCl"_2 + "2H"_2"O}$
This is a neutralization reaction, a type of double replacement reaction. The products are a salt and water. By writing the reactants on the left side as ions, you can see that the hydrogen ion, $\text{H"^+}$, and the hydroxide ion, $\text{OH"^-}$ combine to form water.
$\text{2H"^+ + "2Cl"^(-) + "Mg"^(2+) + "2OH"^(-)}$$\rightarrow$$\text{MgCl"_2 + "H"_2"O}$
