The strength of 11.2 volume solution of H₂O₂ is : [Given that molar mass of H = 1 g mol–1 and O = 16 g mol^–1]

Among the statements (a) - (d), the correct ones are : (a) Decomposition of hydrogen peroxide gives dioxygen. (b) Like hydrogen peroxide, compounds, such as KCIO₃, Pb(NO₃)₂ and NaNO₃ when heated liberate dioxygen. (c) 2-Ethylanthraquinone is useful for the industrial preparation of hydrogen peroxide. (d) Hydrogen peroxide is used for the manufacture of sodium perborate.

Hydrogen peroxide, in the pure state, is :

(A) HOCI + H₂O₂ → H₃O⁺ + Cl⁻ + O₂ (B) I₂ + H₂O₂ + 2OH⁻ → 2I⁻ + 2H₂O + O₂ Choose the correct option.

Which of the following equation depicts the oxidizing nature of H₂O₂?

In basic medium, H₂O₂ exhibits which of the following reactions? (A) Mn²⁺ $$\to$$ Mn⁴⁺ (B) I² $$\to$$ I^$$-$$ (C) PbS $$\to$$ PbSO₄ Choose the most appropriate answer from the options given below :

Given below are two statements : One is labelled as Assertion A and other is labelled as Reason R. Assertion A : The dihedral angles in H₂O₂ in gaseous phase is 90.2$$^\circ$$ and in solid phase is 111.5$$^\circ$$. Reason R : The change in dihedral angle in solid and gaseous phase is due to the difference in the intermolecular forces. Choose the most appropriate answer from the options given below for A and R.
