Reagents used to precipitate potassium salts include sodium tetraphenylborate, hexachloroplatinic acid, and sodium cobaltinitrite into respectively potassium tetraphenylborate, potassium hexachloroplatinate, and potassium cobaltinitrite. The reaction with sodium cobaltinitrite is illustrative:
- 3 K+
+ Na
3[Co(NO
2)
6] → K
3[Co(NO
2)
6] + 3 Na+
The potassium cobaltinitrite is obtained as a yellow solid.
