Questions and Answers

What is the key difference between a strong acid and a weak acid in terms of ionization?

A strong acid ionizes completely in water, while a weak acid ionizes only partially.

Give an example of a strong acid and explain why it is considered strong.

HCl is a strong acid because it ionizes almost completely in water to give H+ and Cl- ions.

Provide an example of a weak acid and describe its ionization behavior.

HF is a weak acid. When hydrogen fluoride gas is passed through water, only some of it ionizes to give H+ and F- ions.

Explain why some acids are classified as weak acids.

<p>Weak acids are classified as such because they do not fully ionize in water, with some of the ions recombining to form molecules.</p> Signup and view all the answers

What happens when a strong acid is dissolved in water?

<p>When a strong acid is dissolved in water, almost all the molecules ionize to release H+ and anion ions.</p> Signup and view all the answers
