hydroxide solubility
What hydroxide solubility means in Chemistry A-Level, as defined for AQA.
Definitions of hydroxide solubility
Exam boards and our study guides word this term in slightly different ways. Learn the version your board uses.
Check what you remember
Read the wording for your board, then hide it and explain hydroxide solubility in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Sodium hydroxide is very soluble, whereas magnesium hydroxide is sparingly soluble, so few OH⁻ ions get into solution.
Solubility of the hydroxide increases down the group, so the resulting solutions become more strongly alkaline.
Topics that use hydroxide solubility
- Group 2, the alkaline earth metals (AQA A-Level)
- Properties of Period 3 elements and their oxides (A-level only) (AQA A-Level)
