Question

Which of the following products is formed when phosphine is absorbed in copper sulphate solution?

• A. $Cu{\left(OH\right)}_2$
• B. $\left[Cu{\left(P{H}_3\right)}_4\right]S{O}_4$
• C. $C{u}_3{P}_2$
• D. $C{u}_3{\left(P{O}_4\right)}_2$

Answer 1

The correct option is C $C{u}_3{P}_2$

$3CuS{O}_4+2P{H}_3\to {Cu}_3{P}_2+3H_{2}S{O}_4$

Hence option $C$ is correct.
