Question 1

Which of the following best describes what happens when hydrochloric acid ($$\mathrm{HCl}) $$dissolves in water?

Accepted Answer

It donates an additional $$\mathrm{H^+} to $$the solution.

Question 2

What is the correct dissociation equation for hydrochloric acid ($$\mathrm{HCl}) in $$water?

Accepted Answer

$$\mathrm{HCl} \rightarrow \mathrm{H^+} + \mathrm{Cl^-}$$

Question 3

Which of the following statements about bases is correct?

Accepted Answer

Bases reduce the hydrogen ion concentration in a solution.

Question 4

How does sodium hydroxide ($$\mathrm{NaOH}) $$act as a base in water?

Accepted Answer

By dissociating to form $$\mathrm{OH^-}$$ ions.

Question 5

Which equation correctly represents the dissociation of sodium hydroxide ($$\mathrm{NaOH}) in $$water?

Accepted Answer

$$\mathrm{NaOH} \rightarrow \mathrm{Na^+} + \mathrm{OH^-}$$

Question 6

If you add a base to a solution, what happens to the $$\mathrm{H^+}$$ and $$\mathrm{OH^-}$$ ion concentrations?

Accepted Answer

$$\mathrm{H^+}$$ decreases, $$\mathrm{OH^-}$$ increases

Question 7

Which of the following is a property of a strong acid?

Question 10

Which of the following is a real-world example of a strong base used in industry?

Accepted Answer

Sodium hydroxide ($$\mathrm{NaOH})$$

Question 11

Which of the following would result if you add a strong acid to a solution containing a strong base?

Accepted Answer

The $$\mathrm{H^+}$$ and $$\mathrm{OH^-}$$ ions neutralize each other.

Question 12

Which of the following is NOT a way that a base can reduce the hydrogen ion concentration in a solution?

Accepted Answer

By donating $$\mathrm{H^+}$$ ions.

Question 13

Which of the following best describes a weak acid?

Accepted Answer

It partially dissociates in water.

Question 14

A student adds $$\mathrm{NaOH} to a $$beaker of water. What is the immediate effect on the solution?

Accepted Answer

The $$\mathrm{OH^-}$$ concentration increases.

Question 15

Which of the following is true about the relationship between acids, bases, and $$\mathrm{pH}$$?
