उत्तर
Applications of coordination compounds:
1) In medicine:
- Cisplatin [PtCl2(NH3)2] is useful in treatment of cancer.
- EDTA is useful in treatment of poisoning by lead.
2) In electroplating
Stable complexes with very small dissociation in solution are used for electroplating with silver and gold.
- The complex K[Ag(CN)2] is used for electroplating with silver
- The complex K[Au(CN)2] is used for electroplating with gold
