प्रश्न
Ammonia is a good complexing agent. Explain.
उत्तर
- The lone pair of electrons on the nitrogen atom facilitates the complexation of ammonia with transition metal ions. Thus, ammonia is a good complexing agent as it forms a complex by donating its lone pair of electrons.
- \[\ce{\underset{(Blue)}{Cu^2+_{ (aq)}} + 4NH_{3(aq)}->\underset{(Deep blue)}{[Cu(NH3)4]^2+_{( aq)}}}\]
- \[\ce{\underset{(White)}{AgCl_{(s)}} + 2NH_{3(aq)}->\underset{(Colourless)}{[Ag(NH3)2]Cl_{( aq)}}}\]
- This reaction is used for the detection of metal ions such as Cu2+ and Ag+.
