Question

${Cu}^{2+}$ gives white ppt of ${Cu}_2{I}_2$ with $KI$ and deep blue colour of $[{Cu\left({NH}_3\right)}_4{]}^{2+}$ with aq.${NH}_3$ (excess).

If the given statement is true enter 1 else enter 0.

Answer 1

${Cu}^{2+}$ gives white ppt of ${Cu}_2{I}_2$ with $KI$. and deep blue colour of $[{Cu\left({NH}_3\right)}_4{]}^{2+}$ with aq.${NH}_3$ (excess)
$2C{u}^{2+}+2KI\to C{u}_2{I}_2\downarrow \left(whiteppt\right)+2K^{+}$
$C{u}^{2+}+4N{H}_3\to \left[Cu\right(N{H}_3{)}_4{]}^{2+}$
