1. `Cl_(2)O and ClO_(2)` are used as bleaching agents.
2. `Ocl^(-)` salts are used as detergents
3. `OCl^(-1)` disproportionates in alkaline medium.
4. `BrO_(3)^(-)` is oxidised in acidic medium.

A

1, 2, 3 correct

B

2, 3, 4 correct

C

1,2, 4 correct

D

1, 3, 4 correct

Text Solution

Verified by Experts

The correct Answer is:
A
Among the given statements:
1. `Cl_(2)O and ClO_(2)` give nascen oxygen, thus behave as bleaching agent.
2. Salts of `Ocl^(-)` are used as detergents.
3. Oxidation state of Cl in `Ocl^(-)` is (+1), thus it shows disproportionation reaction in acidic medium.
`underset(+1)(5ClO^(-)) (5HClO) rarr underset([0])(2Cl_(2))+ underset([+5])(ClO_(3)^(-)) (HClO_(3)) + 2H_(2)O`
4. `BrO_(3)^(-)` does not oxidise in acidic medium. Thus (a) is the correct answer.
