Application (8 marks) 6. If 1.0 L of a hypochlorous acid acid/sodium hypochlorite buffer is prepared using 0.50 mol hypochlorous acid and 0.50 mol sodium hypochlorite. a) Write the balanced chemical equation for the buffer solution at equilibrium. (1 mark) b) Write the Ka expression for the buffer solution. (1 mark) c) Calculate the initial pH of the buffer solution. (2 marks) c) Would this buffer solution be effective for each of the following additions? Assume no change in volume. Explain with the use of reaction equations. (4 marks) (i) 0.75 mol of NaOH (ii) 0.40 mol of HCI
