Sodium Cobaltnitrate AR 250g
Sodium Cobaltinitrite (Na3Co(NO2)6) is primarily used as a reagent in chemical analysis for the qualitative detection of potassium and ammonium ions.
It’s also employed in geochemical analysis to distinguish between different types of feldspars.
Here are more detailed Sodium Cobaltnitrate AR 250g uses:
1. Qualitative Detection of Potassium and Ammonium Ions:
Sodium Cobaltinitrite reacts with potassium and ammonium ions to form a yellow, crystalline precipitate (potassium sodium cobaltinitrite, KNa2Co(NO2)6).
This reaction is a classic test in qualitative inorganic analysis to identify the presence of these ions in a sample.
The precipitate’s color and solubility characteristics help confirm the presence of potassium or ammonium ions.
2. Geochemical Analysis:
In thin sections of rocks, sodium cobaltinitrite can be used to differentiate between alkali feldspars (which contain potassium) and plagioclase feldspars (which contain calcium and other ions).
The reaction of sodium cobaltinitrite with the potassium-containing alkali feldspars results in a distinctive coloration that helps in identification.
Other Uses:
Surface Treatment:
Sodium Cobaltinitrite can be used as a corrosion inhibitor in various applications.
Formulations and Other Industries:
It has applications in areas like water treatment, battery production, and the manufacture of dyes and textiles.
Sodium Cobaltinitrite is also used in the Detection Potassium,For the detection of potassium with which it forms a slightly soluble compound. 220 °C (dec.)( lit.) Sodium Cobaltinitrite LR AR is a water-soluble compound which is most commonly utilized for determination of potassium, ammonium, & thallium ions.
