What is the difference between a strong acid and a weak acid? (2 points)
a. a strong acid has a higher ph than a weak acid.
b. a strong acid is 100% ionized; a weak acid is less than 100% ionized.
c. a strong acid is diprotic or triprotic; a weak acid is monoprotic.
d. a strong acid has a greater concentration of hydroxide ions compared to a weak acid.

The correct answer is Option b.

Explanation:

An acid is defined as the substance which looses hydrogen ions when dissolved in water.

A strong acid is defined as the substance which gets completely dissociated into its ions when dissolved in water. Their percentage ionization is equal to 100 %. For Example: etc.. They can be monoprotic, diprotic or tripotic.

A weak acid is defined as the substance which does not get completely dissociated into its ions when dissolved in water. Their percentage ionization is less than 100 %. For Example: etc.. They can be monoprotic, diprotic or tripotic.

Hence, the correct answer is Option b.
