buffer solution is prepared as described in (a) below. To a sample of this buffer solution is added a solution of a strong base as described in (b). (a) 100 mL of 0.18 M benzoic acid are mixed with 0.018 moles of sodium benzoate plus 100 mL of water. (b) 1.0 mL of 0.49 M KOH is added to 50 mL of the solution described in part (A). For each of these solutions calculate: () the molar concentration of benzoic acid. (ii) the molar concentration of benzoate ion. (iii) the pH of the resulting solution. The Ka of benzoic acid is 6.5 x 105. In the lab manual in the section of "Making a Buffer to a Given pH' the buffer you will be required to prepare will have a pH of 4.37. Make note
