a solution is prepared by dissolving a 90.0 g of benzoIc acid (HC7H5O2) and 90.0 g of sodium benzoate (NaC7H5O2) in enough water to give total volume of 500 ml
a. calculate the pH of the solution?
b. A 10.0 ml sample of 0.50 M HCl is added to 90.0 ml of the solution from part (a). assuming volumes are additve, calculate the pH of the solution.?
C. you are tasked with making exactly 5.00L of a pH 4.50 buffer using 1.0 M benzoic acid and 1.5 M sodium benzoate solutions. what volume of each solution will you need to use to prepare this buffer.?
