SODIUM COBALTINITRITE AR
SKU: RXSOL-60-6605-493
Sodium cobaltinitrite is inorganic compound with the formula Na3Co(NO2)6. The anion of this yellow-coloured salt consists of the transition metal nitrite complex [Co(NO2)6]3-. It was a reagent for the qualitative test for potassium and ammonium ions.
Application
Although the sodium cobaltinitrite is soluble in water, it forms the basis of a quantitative determination of potassium, thallium, and ammonium ions. Under the recommended reaction conditions the insoluble double salt, K2Na[Co(NO2)6]·H2O is precipitated and weighed.
