Definition of Partial dissociation of weak acids
Check what you remember
Read the wording for your board, then hide it and explain Partial dissociation of weak acids in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
A weak acid such as CH₃COOH is only partially dissociated, so the mixture contains a substantial reservoir of undissociated CH₃COOH molecules.
