Sodium Cobaltnitrate AR 500g

Sodium Cobaltnitrate AR 500g

Sodium Cobaltinitrite (Na3Co(NO2)6) is primarily used for qualitative testing for potassium and ammonium ions. It forms a slightly soluble precipitate with these ions, allowing for their detection. Additionally, it's used in various applications, including geochemical analysis to distinguish between different types of feldspars.
Here's more detailed breakdown of Sodium Cobaltnitrate AR 500g uses:
Analytical Chemistry:
Potassium and Ammonium Detection: Sodium cobaltinitrite is a reagent used to detect the presence of potassium and ammonium ions in solutions. It reacts to form a complex, which is then used for qualitative analysis.
Geochemical Analysis:
Distinguishing Feldspars: In the analysis of thin sections of rocks, sodium cobaltinitrite can help differentiate between alkali feldspars and plagioclase feldspars.
Other Potential Applications:
Nitrosation Reagent: It can be used as a nitrosation reagent for the conversion of aromatic amines to 1,3-diaryltriazenes.
Catalyst: Some resources mention its use as a catalyst in certain processes.
Surface Treatment: While not explicitly stated as a primary use, it is mentioned in the context of surface treatment, potentially as a corrosion inhibitor or related application.

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.
