What is electrolyte cell ? Give its uses. |
|
Answer» Solution :* In an electrolytic cell external source of voltage is used to bring about a chemical reaction. In electrolytic cell external electrical energy get converted into chemical energy. * Uses : Electrochemical process is USEFUL in laboratory as WELL as in chemical industries. Some uses are given as follows: (i) For purification of metals : e.g., impure copper gets converted into copper with high purity. this is the basis of it and for this, impure copper copper gets converted into copper with high purity. this is the basis of it and for this, impure copper metal is used as anode which on passing of DC current, it get dissolved and `Cu^(2+)` of solution get reduced and deposited on CATHODE. (ii) For production of metals in large quantity: e.g., metals like Na, Mg and Al can be obtained by reduction of such large metal ions. it is very useful then sodium and magnesium metals can be obtained by electrolysis of their MOLTEN CHLORIDES. Al can be produced by electrolysis of alumnium oxides in presence of aluminium cryolite. |
