Question

Reaction between $N{H}_3$ and $\left[Cu\right(H_{2}O{)}_4{]}^{2-}$ is spontaneous. State whether the state is true or false.

Answer 1

Given statement is true.

Reaction between $N{H}_3$ and $\left[Cu\right(H_{2}O{)}_4{]}^{2-}$ is spontaneous.

When $\left[Cu\right(H_{2}O{)}_4{]}^{2-}$ reacts with excess ammonia,a deep blue solution is formed of the ammine complex ion, $\left[Cu\right(N{H}_3{)}_4(H_{2}O{)}_2{]}^{2+}$.
