Question:
Identify the correct statements from the following:
I. \( H_2O_2 \) oxidizes PbS to \( PbSO_4 \)
II. \( H_2O_2 \) is used in the industrial preparation of sodium perborate
III. \( H_2O_2 \) is insoluble in water
Identify the correct statements from the following:
I. \( H_2O_2 \) oxidizes PbS to \( PbSO_4 \)
II. \( H_2O_2 \) is used in the industrial preparation of sodium perborate
III. \( H_2O_2 \) is insoluble in water
II. \( H_2O_2 \) is used in the industrial preparation of sodium perborate
III. \( H_2O_2 \) is insoluble in water
Show Hint
- \( H_2O_2 \) is a strong oxidizing agent and can oxidize PbS to PbSO_4.
- It is used industrially in the production of sodium perborate.
- \( H_2O_2 \) is soluble in water due to hydrogen bonding.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Use conceptual properties of H_2O_2
(I) Oxidation of PbS:
H_2O_2 acts as a strong oxidizing agent and converts sulfides to sulfates. Hence, this statement is correct.
(II) Industrial use:
H_2O_2 is used in the preparation of sodium perborate used in detergents. Hence, this statement is correct.
(III) Solubility in water:
H_2O_2 forms hydrogen bonds with water, making it highly soluble. Therefore, saying it is not soluble is incorrect.
Final Answer: \mathbf{(1)\ I,\ II\ only}
