What volume of 0.0658 M calcium hydroxide is required to neutralize 45.10 mL of 0.0242 M nitric acid?

1 answer

the famous titration equation:

Na*volumeAcid=Nb*volumeBase

where N is concentration in Normality. Normality equals Molarity times Heq+.

Nitric acid HNO3 is ONE H+
Ca(OH)2 is TWO H+ equivalents

1*.0658 Va=2*.0242*.45.10 ml

solve for Va
