1) Calculate the ratio of CH3NH2 to CH3NH3Cl required to create a buffer with pH=10.26

Part A: What is the pH of a buffer prepared by adding 0.405mol of the weak acid HA to 0.608mol of NaH in 2.00L of solution? The dissociation constant Ka of HA is 5.66e-7

Part B: What is the pH after 0.150mol of HCL is added to the buffer from part A? Assume no volume change on the addition of the acid.

Part C: What is the pH after 0.195mol of NaOH is added to the buffer form part A? Assume no volume change on the addition of the base
