Question 1
Calculate the pH for an aqueous solution of pyridine that contains 2.15 × 10
-4 M hydroxide ion.
◦ 3.67
◦ 2.15 × 10
-4 ◦ 4.65 × 10
-11 ◦ 10.33
Question 2
What is the hydroxide ion concentration and the pH for a hydrochloric acid solution that has a hydronium ion concentration of 1.50 × 10
-4 M?
◦ 6.67 × 10
-11 M, 10.18
◦ 6.67 × 10
-10 M, 4.82
◦ 6.67 × 10
-11 M, 3.82
◦ 6.67 × 10
-10 M, 9.18
