**C5. Electricity and chemistry**
**Assessment Statement.** //All candidates should be able to:// || ======Covered in Class====== || ======Revised @ home====== || ======I am certain====== || ======I need help====== ||
 * ======Serial No====== || ====== ======
 * 1 || ======State that electrolysis is the chemical effect of electricity on ionic compounds, causing them to break up into simpler substances, usually elements.====== ||  ||   ||   ||   ||
 * 2 || ======Use the terms //electrode//, //electrolyte//, //anode// and //cathode.//====== ||  ||   ||   ||   ||
 * 3 || ======Describe electrolysis in terms of the ions present and the reactions at the electrodes.====== ||  ||   ||   ||   ||
 * 4 || ======Describe the electrode products, using inert electrodes, in the electrolysis of:======

• dilute sulfuric acid.
||  ||   ||   ||   ||
 * 5 || ======State and use the general principle that metals or hydrogen are formed at the negative electrode (cathode), and that non-metal (other than hydrogen) are formed at the positive electrode (anode).====== ||  ||   ||   ||   ||
 * 6 || ======Relate the products of electrolysis to the electrolyte and electrodes used, exemplified by the specific examples in the Core together with aqueous copper(II) sulfate using carbon electrodes and using copper electrodes (as used in the refining of copper).====== ||  ||   ||   ||   ||
 * 7 || ======Describe the electroplating of metals, using laboratory apparatus.====== ||  ||   ||   ||   ||
 * 8 || ======Predict the products of the electrolysis of a specified binary compound in the molten state, or in aqueous solution.====== ||  ||   ||   ||   ||
 * 9 || ======Describe, in outline, the chemistry of the manufacture of:======

• chlorine, hydrogen and sodium hydroxide from concentrated aqueous sodium chloride.
