Answer:
(a) Most liquids that conduct electricity are solutions of ___salts_____, ___acids____ and __bases______.
(b) The passage of an electric current through a solution causes ___chemical______ effects.
(c) If you pass current through copper sulphate solution, copper gets deposited on the plate connected to the __negative____ terminal of the battery.
(d) The process of depositing a layer of any desired metal on another material by means of electricity is called ___electroplating______.
a) Acids, bases and salts are electrolytes as they contains ions causing ionisation and dissociation.
b) Chemical reaction occurs when electric current is passed through a conducting solution , causing gas bubbles, metal deposition on electrodes.
c) Due to the positive charge of copper metal it gets deposited in negative terminal of battery.
d) Electroplating reduces the dissolved metal cations and hence forms a coating on electrode.
