Question

When aluminium phosphide is reacted with dil. $H_{2}S{O}_4$ :

• A. $S{O}_2$ is liberated.
• B. $P{H}_3$ is evolved.
• C. $H_{2}S$ is evolved
• D. $H_2$ is evolved.

Answer 1

Answer: (B)

$P{H}_3$ is evolved.

When alluminium Phospide reacts with $H_{2}S{O}_4$ it gives $P{H}_3\left(Phosphine\right),A{l}_2(S{O}_4{)}_3$

$2AlP+dil.3H_{2}S{O}_4\to A{l}_2(S{O}_4{)}_3+2P{H}_3$.

Hence option B is correct.
