(ii) Option (d) is correct.

(iii) Option (d) is correct

(iv) Option (c) is correct.

(v) Option (b) is correct.

(vi) Option (a) is correct.

(vii) Option (b) is correct

(viii) Option (d) is correct.

(x) Option (c) is correct

(xi) Option (b) is correct.

(xii) Option (c) is correct

(xiii) Option (b) is correct

(xiv) Option (c) is correct.

(xv) Option (b) is correct.

Answer-2.

(i) (a) The metal which is to be electroplated should always be at cathode in electroplating.
Therefore, the metal ion (Ni2+) in it gets reduced at the cathode and forms a layer on it.

(b) Cation: Ni2+ and anion depend upon the electrolyte taken.

(c) The passage of low current for long time is a necessary condition to ensure the deposit is smooth, even and firm.

(d) Ni2+ + 2e– ® Ni

(e) Negatively charge ions (depends upon the electrolyte) move toward the anode but do not discharged due to nature of the electrode. But Ni losses two electrons converted into Ni2+ in the solution. That results anode electrode get thinner and iron cup becomes thicker over the time of electrolysis.

(ii) Column A Column B
(a) Water                     3. Covalent compound
(b) Alkali metal        1. Lithium
(c) Halogen                 2. lodine
(d) Calcium oxide    5. lonic compound
(e) Weak acid           3. Acetic acid

(iii) (a) FeCl3
(b) Al2O3
(c) Copper nitrate
(d) Copper
(e) Calcination

(iv) (a) Alkyl group
(b) Electrodes (cathode and anode)
