Question

Which of the following act as a stabilizer for the storage of $H_2{O}_2$?

• A. Alkali
• B. Dust
• C. Urea
• D. None of these

Answer 1

The correct option is C Urea

For removing the gangue from sulphide ores, some chemical compounds called as stabilizers are used in flotation method. For getting satisfactory bleaching action from hydrogen peroxides, alkalis are added to make it alkaline. Thus, urea is added in the storage of $H_2{O}_2$ to stabilize the alkaline dilute solution of $H_2{O}_2$ which is unstable.

Answer: (C) Urea
