integration ratios
What integration ratios means in Chemistry A-Level, as defined for AQA.
Definition of integration ratios
Check what you remember
Read the wording for your board, then hide it and explain integration ratios in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Give the relative numbers of equivalent protons in the molecule, never the absolute number, so a ratio needs the molecular formula before it becomes a structure.
