Please give calculation with explanation.
A solution of pH 3.88 is prepared by dissolving sufficient sodium formate, NaHCOO(s), in 1.50 L of 0.100 M formic acid (HCOOH). How many mol of NaOH(s) must be added to change the pH by 0.40 units? Assume no volume changes on addition of solids. Data: Ka (HCOOH) = 1.8 × 10-4 0.025 0.10 0.070 0.040
