We want to prepare a buffered solution having a pH of 4.97 using concentrated (23.6 M) formic acid (HCOOH) and solid sodium formate (HCOON)). K, for formic acid is 1.8 x 10-4. Your Answer Correct Answer (Used) Calculate the ratio [HCOO (aq)] / [HCOOH(aq)] in the buffered solution required to achieve a pH of 4.97. [HCOO (aq)] / [HCOOH(aq)] = 17.0 If the total molarity of formic acid plus formate ion in the buffered solution is 0.200 M, calculate the volume of concentrated acid and mass of sodium formate that must be dissolved in 1.00 L of water. i mL formic acid g sodium formate
