How many milliliters of 3.00 M hydrochloric acid would be needed to react completely with a milk of magnesia tablet that contains 310 mg of Mg(OH)2? The neutralization reaction produces magnesium chloride, MgCl2, and water.
First we need a chemical equation.
HCl + Mg(OH)2 -----> MgCl2 + H2O
We know this is true because we have an acid/base reaction, which produces a salt and water. Now we need to balance it:
2 HCl + Mg(OH)2 -----> MgCl2 + 2 H2O
Now we can answer the question. All of these ...
