Question

Among statement (1) - (4), the correct ones are (1) Decomposition of hydrogen peroxide gives dioxygen. (2) Like hydrogen perioxide, compound, such as KClO 3, Pb ( NO 3)2 and NaNO 3 when heated liberate dioxygen. (3) 2-Ethylanthraquinone is useful for the industrial preparation ofhydrogen peroxide. (4) Hydrogen peroxide is used for the manufacture of sodium per borate (A) (1) and (3) only (B) (1), (2), (3) and (4) (C) (1), (3) and (4) only (D) (1), (2) and (3) only

Tardigrade Admin · Accepted Answer

All these statements are correct as on decomposition hydrogen peroxide and compounds, such as

K Cl O_{3}, P b (N O_{3})_{2}

and

N a N O_{3}

when heated liberate dioxygen

2 H_{2} O_{2} \to Δ 2 H_{2} O + O_{2}

2 K Cl O_{3} \to Δ 2 K Cl + 3 O_{2}

2 N a N O_{3} \to Δ 2 N a N O_{2} + O_{2}

Both 3 and 4 statements are correct as 2-Ethylanthraquinone is useful for the industrial preparation of hydrogen peroxide and hydrogen peroxide is used for the manufacture of sodium per borate.
