How are pure samples of potassium amide
Did you know?
Potassium amide is an inorganic compound with the chemical formula KNH2. Like other alkali metal amides, it is a white solid that hydrolyzes readily. It is a strong base. Ver mais Potassium amide is produced by the reaction of ammonia with potassium. The reaction typically requires a catalyst. Ver mais Traditionally KNH2 is viewed as a simple salt, but it has significant covalent character and is highly aggregated in ammonia solution. The compound has been characterized by X-ray crystallography as the solvent-free form as well as the mono- … Ver mais WebSilver nitrate solution and sodium chloride solution (or potassium chloride solution, or ammonium chloride solution).

The compound may have evaporated. A TLC plate should be visualized immediately after elution, so if a moderate amount of time was left between running the TLC and visualizing it, evaporation may be the cause of the problem. A solution to this problem is to run the TLC again and visualize it immediately.
