STATEMENT BASED
(1) Both Statement-I and Statement-II are correct.
(2) Both Statement-I and Statement-II are incorrect.
(3) Statement-I is correct and Statement-II is incorrect.
(4) Statement-I is incorrect and Statement-II is correct.
Statement-I: The number of moles of \( \mathrm{KMnO}_{4} \) that will be needed to react with 1 mole of \( \mathrm{HCN} \) (While \( \mathrm{HCN} \) oxidizes into \( \mathrm{C}_{3}^{2} \) and \( \mathrm{NO}_{3}^{-} \)) in an acidic medium is 0.5 .
Statement-II: Because the \( \mathrm{n} \)-factor of \( \mathrm{KMnO}_{4} \) in an acidic medium is 5 and the \( \mathrm{n} \)-factor of \( \mathrm{HCN} \) is 10 . So, the molar ratio of \( \mathrm{KMnO}_{4} \) to \( \mathrm{HCN} \) is \( 1: 2 \).
