Question

Fill in the blanks
(a) Most liquids that conduct electricity are solutions of _________, _________ and _________ .
(b) The passage of an electric current through a solution causes _________ effects.
(c) If you pass current through copper sulphate solution, copper gets deposited on the plate connected to the _________ terminal of the battery.
(d) The process of depositing a layer of any desired metal on another material by means of electricity is called _________ .

Answer 1

(a) Most liquids that conduct electricity are solutions of acids, bases and salts.
(The solutions of acids, bases or salts are conducting in nature. They allow the current to pass through)

(b) The passage of an electric current through a solution causes chemical effects.
(When an electric current passes through a solution, the solution decomposes into its positive and negative ions)

c) If you pass current through copper sulphate solution, copper gets deposited on the plate connected to the negative terminal of the battery.

(When electric current is passed through a copper sulphate solution, the solution decomposes into positively charged and negatively charged ions. These positively charged ions get attracted towards the negative plate)

(d) The process of depositing a layer of any desired metal on another material by means of electricity is called electroplating.
(Electroplating is the deposition of metal on other material)
