The main application of the electrolytic cell is for the industrial production of high-purity metals. It is a device that converts electrical energy into chemical energy (composition: external power supply, electrolyte solution, anode and cathode). The process of passing a current through an electrolytic solution or a molten electrolyte to cause a reduction oxidation reaction at the anodic and anodic poles.
Cell
Note for electrolytic cells
Anaerobic acid is its own electrolysis
Oxygen is the electrolysis of water
Soluble alkali is the electrolysis of water
Oxygenates of active metals are also the electrolysis of water
Hydrogen precipitates from the cathode of the active metal, and the solution becomes alkaline with the solution, and non-metallic elements precipitate from the anode
An oxygen-free salt of an inactive metal is the electrolysis of that salt
Oxide salts of moderately active metals precipitate metals at the cathode, and the anode receives oxygen while increasing acidity
Electrolytic cell memory method
Oxygen halide at the anode and hydrogen metal at the cathode.
The ions of the salt are discharged, and the ion concentration decreases rapidly;
Salt ions do not discharge, water consumption increases ion concentration.
Single discharge of acid ion, the product will get halobase;
Single discharge of metal ions will produce oxyacid.
