A black mineral (A) in solid state is fused with KOH and KNO3 and the mixture extracted with water to get a green coloured solution (B). On passing CO2 gas through the solution the colour changes to pink with a black residue (C). Which of the following is/are correct
  • a)
    The Pink coloration is decolourised by acidified ferrous sulphate solution
  • b)
    The black residue is same as compound (A)
  • c)
    When O3 is passed through the green colour solution is changes to pink.
  • d)
    Shape of the anion of pink substance is tetrahedral
Correct answer is option 'A,B,C,D'. Can you explain this answer?

Explanation:

b) The black residue is same as compound (A)

- The black mineral (A) in solid state, when fused with KOH and KNO3, forms a green coloured solution (B).
- When CO2 gas is passed through this solution, the colour changes to pink with the formation of a black residue (C).
- The black residue (C) is likely to be the same compound as the original black mineral (A) due to the chemical reactions involved in the process.

a) The pink coloration is decolourised by acidified ferrous sulphate solution

- The pink coloration seen when passing CO2 gas through the green solution is indicative of the formation of a specific compound.
- Acidified ferrous sulphate solution is known to decolourize pink coloration, suggesting that the pink substance formed in the reaction can be decolourized by this solution.

c) When O3 is passed through the green colour solution, it changes to pink

- The change in color from green to pink upon passing O3 through the green solution further confirms the presence of a specific compound formed during the reaction process.

d) Shape of the anion of pink substance is tetrahedral

- The tetrahedral shape of the anion of the pink substance can be inferred from the chemical properties and reactions observed during the experiment.

Therefore, all the given options (A, B, C, D) are correct based on the chemical reactions and observations made during the experiment.
