Problem: Consider a 1.0 L stock solution of 1.50 M acetic acid. The ?Ka? ?of acetic acid is 1.8 x 10-? 5?.
Required:
Question 1: What is the approximate pH of the acetic acid stock solution?
Question 2: What is the percent ionization of the stock solution?
Question 3: Imagine that you obtain a 20.0 mL sample of acetic acid from the stock and that you mix it with 180.0 mL of 0.125 M NaOH in order to make a buffer. What would be the pH of this buffer?
Question 4: What would be the equivalence point of the sample if you continued to titrate it with 0.100 M NaOH?
AgCl is a sparingly soluble salt, with a solubility of about 10-5 M in pure water. Adding KCN increases the solubility of AgCl because: CN- reacts with Ag+ to make a soluble complex.
