Assignment Help Chemistry
Reference no: EM13982766

1. A certain buffer system that contained 15 mL of 0.1M HA and 50 mL of 0.6M A- was found to have a pH of 9. What would be the Ka for that buffer system?

pH= pKa + log[A-]/[HA]

2. Select a pH different from any used in the experiment above. Design a buffer that could create that pH by determining the volumes of the acidic and basic buffer components.
