Question

Acidified solution of a compound a undergoes decomposition on passing electric current through it to produce two gases and c

Answer 1

Answer: Brine,NaCl

Explanation: When an electric current is passed through a solution containing Concentrated NaCl,Chlorine gas is produced at the anode while Hydrogen gas is produced at the cathode.

Answer 2

Acidified solution of NaCl undergoes decomposition on passing electric current through it to produce two gases and C as products.

Explanation:

Here the compound A is NaCl(Sodium Chloride)

When the Sodium Chloride solution is dissolved in water, we get Sodium Chloride solution.

Conducting electrolysis on the NaCl solution we get two type of gases along with Sodium hydroxide as the product.

1. Passing the electric current into the NaCl solution, the Hydrogen H+ molecules in the solution discharged at the negative electrode as H2 gas.
2. On the other side, the Chlorine molecule in the solution discharges at the positive electrode to for Cl2 gas.
3. The leftover Sodium, Hydrogen and Oxygen combine to form Sodium Hydroxide solution.
