Question: Buffer 1 is a solution containing 0.08MNH4Cl and 0.12MNH3. Buffer 2 is a solution containing 0.15MNH4Cl and 0.05MNH. The pKa of the NH4+ion is 9.24.

Buffer 1 is a solution containing 0.08MNH4Cl and 0.12MNH3. Buffer 2

Buffer 1 is a solution containing 0.08MNH4Cl and 0.12MNH3. Buffer 2 is a solution containing 0.15MNH4Cl and 0.05MNH. The pKa of the NH4+ion is 9.24. (a) What are the pH values of each of the buffer solutions? (4 marks) (b) Which buffer is better able to maintain a steady pH on the addition of small amounts of both a strong acid and strong base? Explain. ( 2 mark)
