A simple way to remember a monatomic ion’s oxidation number is to recall the number of electrons it gains or loses, which is based on its group number. A-Level Chemistry does pretty much what it says on the tin. Edexcel A level Topic 14: Redox II Notes: Edexcel Chemistry – Topic 14: Redox II One of the ways we discovered to know if a redox reaction has occurred, you will find that the oxidation numbers of two elements has changed from the reactant side to the product side an example is the formation of hydrogen fluoride. We know this because the oxidation state of magnesium changes from zero (the element) to +2 in MgCl2. Contrary to popular belief, you don’t need to be a chemistry-loving genius that eats, sleeps and drinks the subject 24/7 to get an A*, rather, it takes a lot of hard work and careful preparation that should start from day one. View The Resource. Notes for the Edexcel A level Chemistry module: Topic 14: Redox II. Question number Answer Marks Guidance 1 a (aq) 3CuS(s) +8HNO The change in the oxidation state of an element in a compound or ion is used to identify the element that has been oxidised or reduced in a given reaction. Redox-Reactions-worksheet. You do this by taking a known amount of iodine and titrating it with standard sodium thiosulphate.… Oxidation states show how oxidised or reduced an element is within a compound or ion. The oxidation and reduction reactions are therefore two semi-reactions that are part of this process of electron exchange, which takes the name of redox. Achieving an A* in A Level chemistry is difficult – only around 1 in 10 students achieve this grade each summer. Created by teachers for Chemistry revision. For example: The reaction: Mg(s) + 2HCl(aq) MgCl 2 (aq) + H 2 (g) is a redox reaction.
