The ion formed when excess ammonia is added to cupric salt solution is ________.

Open in App

Solution

The following reaction occurs when excess ammonia is added to cupric salt solution:
${[C u (H_{2} {O)}_{6}]}^{2 +} e x c e s s a m m o n i a - ---------- \to {[C u {{(N H}_{3})}_{4} (H_{2} {O)}_{2}]}^{2 +} + 4 H_{2} O$
Hence, the ion formed when excess ammonia is added to cupric salt solution is ${[C u {{(N H}_{3})}_{4} (H_{2} {O)}_{2}]}^{2 +}$
