Question
Which statements about the strength of bases are true?Multiple select question.Weak bases do not ionize completely.Strong bases dissociate completely.Weak bases do not ionize at all.Strong bases do not ionize completely.
Solution
The correct statements about the strength of bases are:
- Weak bases do not ionize completely.
- Strong bases dissociate completely.
Explanation:
A weak base is a base that does not ionize fully in an aqueous solution. As Brønsted-Lowry bases are proton acceptors, a weak base may also be defined as a chemical base in which protonation is incomplete. This results in a relatively low pH compared to stronger bases.
Strong bases fully dissociate in reaction to water, meaning they donate most or all of their hydroxide ions (OH-) to the solution. This results in a relatively high pH. Examples of strong bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).
