Question

"The species [CuCl${}_4$]${}^{2-}$ exists, while [CuI${}_4$]${}^{2-}$ does not"

If true enter 1,if false enter 0.

• A. 1

Answer 1

The correct option is A 1
"The specics $[CuC{l}_4{]}^{2-}$ exists, while $[Cu{I}_4{]}^{2-}$ does not"
$2Cu{I}_2\to C{u}_2{I}_2+I_2$
Iodide ion reduces $C{u}^{2+}$ to cuprous iodide and $I_2$. So $[Cu{I}_4{]}^{2-}$ does not exist.
