If 25.00 mL of 1.000M HNO^3 is titrated to a neutral endpoint with 36.97 mL of NaOH solution, what is the molarity of the NaOH solution?© BrainMass Inc. brainmass.com October 9, 2019, 4:01 pm ad1c9bdddf
In order to titrate the acid to neutral endpoint, you must add equal moles of base to neutralize the acid. Since NaOH gives off one OH- group and HNO3 gives off one H+, the stoichiometry between base and acid is 1:1. Therefore, at neutral endpoint, moles of acid is equal to the moles ...
The general formula for this type of question is M(base)V(base)=M(acid)V(acid).
