1. You have 125 mL of nitric acid, but you don't know its concentration. To determine the concentration you take a 32.91 mL portion of the acid and titrate it with a 18.75 mM solution of lithium hydroxide. You find that you need 22.03 mL of the base to neutralize the acid. What is the molar concentration of the acid? Show work and explain
2. You wish to neutralize a solution of phosphoric acid by adding to it solid lithium hydroxide. The phosphoric acid solution is 12.74 mL and has a concentration of 0.283 M. What mass of lithium hydroxide must you add to neutralize the solution?
