Given below are two statements: Statement I : Hydrogen peroxide can act as an oxidizing agent in both acidic and basic conditions. Statement II: Density of hydrogen peroxide at 298 K is lower than that of D 2 O . In the light of the above statements. Choose the correct answer from the options.

Options

  1. ABoth statement I and Statement II are ture
  2. BBoth statement I and Statement II are false
  3. CStatement I is true but Statement II is false
  4. DStatement I is false but Statement II is true

Correct answer

C. Statement I is true but Statement II is false

Step-by-step solution

It acts as an oxidising as well as reducing agent in both acidic and alkaline media. Simple reactions are described below. (i) Oxidising action in acidic medium 2 Fe 2 + aq + 2 H + aq + H 2 O 2 aq → 2 Fe 3 + aq + 2 H 2 O l (ii) Reducing action in acidic medium 2 MnO 4 − + 6 H + + 5 H 2 O 2 → 2 Mn 2 + + 8 H 2 O + 5 O 2 (iii) Oxidising action in basic medium 2 Fe 2 + + H 2 O 2 → 2 Fe 3 + + 2 OH - (iv) Reducing action in basic medium I 2 + H 2 O 2 + 2 OH − → 2 I − + 2 H 2 O +
