Question 1

In titrating 0.20 M hydrochloric acid, HCl, with 0.20 M NaOH at 25°C, the solution at the equivalence point is

◦ 0.20 M NaCl
◦ very acidic
◦ slightly acidic
◦ 0.10 M HCl and 0.20 M NaOH
◦ 0.10 M NaCl

Question 2

In titrating 100 mL of 0.10 M HCl (aq) with 0.10 M NaOH, the pH does not change a great deal initially. Why is this?

◦ The amount of OH–has no effect on the pH of aqueous solutions.
◦ The H+ from the HCl (aq) acts like a buffer.
◦ The major species when the acid and base are mixed form a buffered solution.
◦ The statement “In titrating 100 mL of 0.10 M HCl (aq) with 0.10 M NaOH, the pH does not change a great deal initially.” is not true.
◦ None of these are correct.
