Question:
In Merck’s method, \( \mathrm{H_2O_2} \) is obtained from
In Merck’s method, \( \mathrm{H_2O_2} \) is obtained from
Show Hint
Merck’s method specifically uses sodium peroxide for the preparation of hydrogen peroxide.
Updated On: Feb 11, 2026
- \( \mathrm{BaO_2 + H_2SO_4} \)
- \( \mathrm{Na_2O_2 + H_2SO_4} \)
- \( \mathrm{BaO_2 + H_3PO_4} \)
- \( \mathrm{BaO_2 + H_2O + CO_2} \)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding Merck’s method.
Merck’s method is a laboratory method for the preparation of hydrogen peroxide.
Step 2: Reaction involved.
In this method, sodium peroxide reacts with dilute sulphuric acid to form hydrogen peroxide.
Step 3: Eliminating incorrect options.
Barium peroxide methods involve different acids and conditions, not Merck’s method.
Step 4: Conclusion.
Thus, hydrogen peroxide is obtained from sodium peroxide and sulphuric acid.
