Calculate the pH of the benzoic acid solution, (Ka = 6.0 • 10^-5) formed by dissolving 0.34 g of this acid in 100 mL of solution. b) What will the pH be if we mix 100 mL of this acid solution with 200 mL of 0.01 M sodium benzoate solution? Does the pH value change if we add 0.01 mole of H+ to the mixture? c) Show through calculations what happens to the osmotic pressure when we pass from the solution of point (a) to that of point (b).
