Electrolysis Test Study Guide 100% Accurate!!
What are the 8 uses of electrolysis? - ANSWERPurification of metals
Electroplating
Chlorine production
Extraction of Hydrogen from water
Extraction of oxygen from water
Extraction of Reactive metals
Hair removal
Production of sodium hydroxide
What is Electrolysis? - ANSWERThe passing of an electric current through an molten ionic compound
causing a chemical change resulting in a change in the elements that make up the compound.
What is an Electrolyte? - ANSWERA molten ionic compound that undergoes electrolysis.
What is an Anode? - ANSWERA positively charge electrode.
What is a Cathode? - ANSWERa negatively charged electrode.
What is an electrode? - ANSWERan electrical conductor.
(Chem web def: Terminals/sticks that allow electricity to go through them.)
What are the Diatomic elements? - ANSWERH, N, O, F, Cl, Br,I
Or H-NOF-I
What Does being a Diatomic element mean? - ANSWERThis means that a when a comped is split up,
and one of the products of the reaction is a diatomic element then that diatomic element has X₂
Tip: When a compound is spilt up, if it becomes a diatomic element and a metal, the diatomic
element will be a gas (g), while the metal will be a solid (s).
