The reaction Ag2O + H2O2 → 2Ag + H2O + O2 takes place in:
Correct answer: A. Basic medium.
- A. Basic medium.
- B. Bleaching agent.
- C. Neutral medium.
- D. Both in acidic and basic medium.
Explanation
The reaction Ag2O + H2O2 → 2Ag + H2O + O2 is facilitated in a basic medium. Silver(I) oxide is amphoteric, meaning it can react with both acids and bases, but in this reaction, its reactivity is enhanced in a basic medium where it forms a soluble complex with hydroxide ions. This allows the reaction with hydrogen peroxide to proceed, producing silver, water, and oxygen. In acidic or neutral conditions, the reaction is less effective due to the lack of optimum conditions for the dissolution and reactivity of silver(I) oxide.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
