Metal hydroxides Study guides, Class notes & Summaries

A Level Edexcel Chemistry - Topic 4 - Inorganic Chemistry and the Periodic Table Fully updated notes providing drop down answers to self made questions designed from numerous textbooks and exam mark schemes. During my revision, I created these drop down questions and answers by extracting the key information needed to achieve top marks in exams. I achieved a high A* using only these notes. Notes for all other topics have been released on my page :) Hope I can help!
