Galvanising gcse chemistry
WebGalvanising. Galvanising can prevent rusting. It is where a metal, such as iron, is coated by a thin layer of a more rea ctive metal such as zinc. This protects the iron underneath in two ways: Prevents oxygen and water from reaching the iron which prevents rusting as water and oxygen are needed for the rusting to occur. Acts a sacrificial barrier. WebGCSE chemistry naturally leads to A level Chemistry, which is the core A level for Degrees in Chemistry, Medicine, Veterinary Science and Pharmacy.
