1)A solution prepared by adding 0.400 mol of acetic acid (pKa = 4.74) and 0.400 mol of sodium acetate to 100.0 mL of water. The pH of this buffer solution is initially 4.74.

Question

Predict the final pH when 55.0 mL of 1.10 M NaOH is added to solution

2) A solution prepared by adding 0.400 mol of acetic acid (pKa = 4.74) to 100.0 mL of water and then titrating with strong base until a buffer with a 1:1 buffer ratio is produced. The pH of this buffer solution is initially 4.74.

Predict the final pH when 55.0 mL of 1.10 M NaOH is added to solution

3) 100.0 mL of pure water.
