WebJan 24, 2024 · V base = volume of the base. This equation works for acid/base reactions where the mole ratio between acid and base is 1:1. If the ratio were different, as in Ca (OH) 2 and HCl, the ratio would be 1 mole acid to 2 moles base. The equation would now be: M acid V acid = 2M base V base. For the example problem, the ratio is 1:1:
