In a flame test, potassium and its compounds emit a lilac color, which may be masked by the strong yellow emission of sodium if it is also present. Cobalt glass can be used to filter out the yellow sodium color.[9] Potassium concentration in solution is commonly determined by flame photome...

Nitrate/Nitrite Reagents such asnaphtholgreen B, gallocyanine (530nm),pyrogallolred (465nm), safranine O (520nm), and phosphomolybdenum (820nm) have been used for nitrate/nitrite determination. Some applications for determining nitrite are based on the decrease in colour of a complex. For exampl...
a decrease in photosynthetic pigments and variability in the response of phenolic compounds content was recorded, depending on the organ and the K+concentration in the medium. Analysis of the anatomical structure of stems showed that exposure to potassium deficiency in basil decreased the diameter of...

How to Make Potassium Nitrate By Anne Marie Helmenstine, Ph.D. Take care to check the label on the salt substitute to make certain the ingredient is just potassium chloride. While salt substitute is potassium chloride, "lite salt" is a mixture of sodium chloride (table salt) and potassium ...

protocol. The development of yellow color confirmed the presence of phosphorus. The absorbance was taken at 420 nm on a UV-Spectrophotometer for the final determination of phosphorus in the sample [46]. In the analysis of potassium, the digested solution was run directly on a flame photometer ...

(1ml in 36ml water) followed by washing with 1% potassium nitrate solution, until the filtrate is no longer acidic (to litmus). The precipitate was dissolved in 50ml of 1.0mol/L sodium hydroxide solution, phenolphthalein test solution (TS-167) was added several drops, and the remaining ...
