Question

Consider the following statements

(a) Brine is an aqueous solution of NaCl.
(b) Chlorine is used in swimming pools to disinfect water.
(c) $H_2$ is used as a fuel.
(d) During electrolysis of brine, chlorine is obtained at anode.
(e) $H_2$ is liberated at anode during electrolysis of brine.

The correct statements are

• A. a, b, c and e
• B. b, c, d and e
• C. a, c, d and e
• D. a, b, c and d

Answer 1

The correct option is D a, b, c and d

Brine is an aqueous solution of NaCl. When electricity is passed through brine, it decomposes to form sodium hydroxide, which is used for degreasing metals. Chlorine gas, which is used in swimming pools to disinfect water, is liberated at the anode, and hydrogen gas, which is used as a fuel, is obtained at the cathode.

Hence, the correct answer is option (d).
