Answer 1

pA. weak electrolyte - VI ${\mathrm{CH}}_3\mathrm{COOH}$

${\mathrm{CH}}_3\mathrm{COOH}$ (acetic acid) is a weak electrolyte which dissociates to a small extent.

B. Tin - V Tin cans

(a) Tin cans are made by electroplating process in which a conduction material is coated with a thin layer of metal.

(b) Tin cans are coated by ions, used for storing food.

C. Silver - III Water caps

Silver is used in water caps because of the rust proof properties of silver.

D. Gold - II Ornaments

Ornaments are usually made of gold due to highly lustrous property and resistant to corrosion.

E. Chromium - IV Knives

Chromium is a stainless steel which provides hardness, corrosion resistance and wear resistance in making knives.

F. Nickel - I Bathroom fitting
