PEARSON EDEXCEL AS LEVEL CHEMISTRY PAPER 1 MARK SCHEME 2024 (WCH13/01: Practical Skills in Chemistry I)

This document is a detailed and extensive guide for all of the 12 required practicals for AQA A level and AS Level chemistry. Revising the core practicals for exams can be difficult, so I prepared a resource which not only contains the method for each practical but also highlights where specific equipment/techniques/chemicals are being used and explains WHY it is being used (learning these will make core practical-related questions significantly easier). Key observations have additionally been h...
