Calculating volume of acid needed in a reaction

What volume of .320 M HCL (hydrochloric acid) is required to react with 25 mL of .180 M Ba(OH)2 (barium hydroxide)?

Solution Preview


Let us first write down the balanced chemical equation:

2HCl + Ba(OH)2 -->  BaCl2 + 2H2O

From this balanced equation we see that for every mole of Ba(OH)2 we need 2 moles of HCl - twice the amount of Ba(OH)2. So, from the given Ba(OH)2 concentration and given Ba(OH)2 ...
