Question

30.0 mL 0.200 M lithium hydroxide is added to 50 mL of 0.1 M nitrous acid. What is the final pH of the resulting solution?

Answer 1

We prefer you not change screen names. This is worked the same way as the NH4ClO4 problem BUT the LiOH and HNO2 don't neutralize each other completely so you have one of them left over and that determines the pH.
