Question 1: HA is a weak acid. Its ionization constant, Ka, is 5.3 x 10-13. Calculate the pH of an aqueous solution with an initial NaA concentration of 0.079 M.
Question 2: We place 0.148 mol of a weak acid, HA, in enough water to produce 1.00 L of solution. The final pH of the solution is 1.27 . Calculate the ionization contant, Ka, of HA.
Question 3: We place 0.694 mol of a weak acid, HA, and 11.9 g of NaOH in enough water to produce 1.00 L of solution. The final pH of this solution is 4.74 . Calculate the ionization constant, Ka, of HA.
