What is the pH at the equivalence point when when 25.0 mL of 0.175 mol/L HNO2(aq) is titrated with 0.137 mol/L NaOH(aq)? Assume the temperature is 25C. (For HNO2, pKa=3.14 at 25C).
Give your answer accurate to two decimal places.

In this exercise, students are asked to calculate the pH at the equivalence point when a weak acid, HNO2, is titrated with a strong base, NaOH, given the pKa of HNO2.
