Vedclass · Answer

Since, the ammonia has stonger ligand bonds than water with $Cu ^{2+}$. Hence, it can then forms a blue coloured solution of complex salt.

$Cu \left( SO _4\right) \cdot 5 H _2 O +4 NH _4 OH \rightarrow Cu \left( NH _3\right)_4 SO _4 \cdot H _2 O +8 H _2 O$

$Cu ^{2+}+4 NH _3 \rightarrow\left[ Cu \left( NH _3\right)_4\right]^{2+}$

When ammonia is added to a cupric salt solution, the deep blue colour is observed it is due to the formation of
