In its interactions with potassium periodate (KIO4) and hydroxylamine (NH2OH), hydrogen peroxide functions respectively as a

1. substance that donates electrons, substance that accepts electrons
2. substance that donates electrons, substance that donates electrons
3. substance that accepts electrons, substance that accepts electrons
4. substance that accepts electrons, substance that donates electrons

Correct answer: substance that donates electrons, substance that accepts electrons

Solution

The correct answer is that hydrogen peroxide functions as a substance that donates electrons and a substance that accepts electrons because it donates electrons in its reaction with potassium periodate and accepts electrons in its reaction with hydroxylamine.
