Answer 1

7

Question 2

Which of the following is TRUE?

Answer 2

Answer 3

Insufficient information

Question 4

Given Ka (NH4+ ) = 5.6 × 10−10 and Kb(F − ) = 1.4 × 10−11, which best describes the pH of the product?

Answer 4

Acidic

Question 5

Which is not a characteristic of hydrochloric acid (HCl)?

Answer 5

The reaction of HCl with sodium hydroxide will yield only sodium chloride.

Question 6

Which of the following statements is not true regarding acids and bases?

Answer 6

The pH of the salt formed by the reaction between NH3 and HF is neutral.

Question 7

Which of the following reactions would produce a salt that is acidic in solution?

Answer 7

H2SO4 + NH3

Question 8

What is the pH of a solution that is 0.0025 M HCl?

Answer 8

2.60

Question 9

What is the relationship between the value of Ka and the extent to which an acid ionizes?

Answer 9

The larger the value of Ka, the more extensive is the ionization of the acid.

Question 10

Which of the following is an example of a relatively weak acid reacting with a strong base?

Answer 10

Benzoic acid + sodium hydroxide
