Question

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

Answer 1

The products are magnesium chloride and water.

Explanation:

`"2HCl + Mg(OH)"_2"` `rarr` `"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, `"H"^+"`, and the hydroxide ion, `"OH"^-"` combine to form water.

`"2H"^+ + "2Cl"^(-) + "Mg"^(2+) + "2OH"^(-)"` `rarr` `"MgCl"_2 + "H"_2"O"`
