Among statements a - d , the correct ones are: a Decomposition of hydrogen peroxide gives di-oxygen. b Like hydrogen peroxide, compounds, such as K C l O 3 , P b N O 3 and N a N O 3 When heated liberate di-oxygen. c 2 -Ethylanthraquinone is useful for the industrial preparation of hydrogen peroxide. d Hydrogen peroxide is used for the manufacture of sodium perborate.

Step-by-step solution

(a)     H 2 O 2 → 2 H 2 O + O 2 (b)  KClO 3 → Δ KCl + 3 2 O 2 Pb NO 3 2 → Δ PbO + 2 NO 2 + 1 2 O 2 NaNO 3 → Δ NaNO 2 + 1 2 O 2 (c)   2 -   ethylanthraquinol  → O 2 2 − ethylanthraquinone + H 2 O 2 (d)   2 H 3 BO 3 + 2 NaOH + 2 H 2 O 2 → [ Na 2 B 2 O 2 ( OH ) 4 + 4 H 2 O ] All statements are correct
