Calculate,
1,the PH of0.1M CH3COOH buffered solution with 0.2M CH3COONa
2,when 9.5M HClis added to75ml of the buffer solution in(1)
3,compaire the PH of the two questions whre added to pure water?(Ka ofCH3COOH=0.00008)

1. Use the Henderson-Hasselbalch equation.
pH = pKa + log (base)/(acid).
2. How much of the 9.5 M HCl is added?
3. I assume you mean compare when that many mL 0.5 M HCl is added to pure water. How much pure water.
Do #1 first then re post if you still have questions.
