Key Properties
Sodium cobaltinitrite (extra pure) is a soluble cobalt(III) complex salt that serves as a selective precipitating reagent primarily used for the determination of potassium ions in analytical chemistry. This compound is notable for its high purity level of 96%, making it suitable for precise analytical applications. Its unique cobalt(III) complex structure allows it to selectively interact with potassium ions, facilitating accurate gravimetric analysis. The compound is also recognized for its vibrant yellow color, which is characteristic of cobalt compounds, and its ability to form stable complexes in solution.
Also known as Cobalt(III) nitrite, Sodium hexanitrocobaltate.
