Question

Given below are two statements: Statement-I: The oxidation state of phosphorus in the sodium salt of oxoacid formed when white phosphorus reacts with aqueous alkali solution is +1. Statement-II: Sulphur gives two gaseous products when treated with conc. \(HNO_3\).

• A. Both statements I and II are correct
• B. Statement I is correct but statement II is not correct
• C. Statement I is not correct but statement II is correct
• D. Both statements I and II are not correct

Hint:

Remember the reaction: \[ P_4 + 3NaOH + 3H_2O \rightarrow PH_3 + 3NaH_2PO_2 \] The oxidation state of phosphorus in hypophosphite ion \((H_2PO_2^-)\) is \(+1\). This is a frequently asked examination fact.

Answer 1

The Correct Option is B
