Learners match electrodes and identify the process name, determine products at the cathode and anode for ionic and aqueous solutions, and explain why electrode materials may need replacement. Questions also address metal extraction, aluminium manufacture, and factors controlling which ions discharge.","Visit [http://www.mathsmadeeasy.co.uk/](http://www.mathsmadeeasy.co.uk/ for more fantastic)[ for more fantastic](http://www.mathsmadeeasy.co.uk/ for more fantastic) resources.  \n\n| AQA, OCR, Edexcel |\n| --- |\n| GCSE Science |\n\nGCSE Chemistry  \nElectrolysis Questions  \nTotal Marks: /33  \nMaths Made Easy © Complete Tuition Ltd 2017  \n\n| Visit [http://www.mathsmadeeasy.co.uk/](http://www.mathsmadeeasy.co.uk/ for more fantastic)[ for more fantastic](http://www.mathsmadeeasy.co.uk/ for more fantastic) resources.\u003Cbr>Q1: When an ionic compound is melted or dissolved in water, what happens to the ions?\u003Cbr>(1 mark)\u003Cbr>Q2: Define an electrolyte.\u003Cbr>(2 marks)\u003Cbr>Q3: Passing an electric current through electrolytes causes the ions to move to electrodes.
