We usually detect the presence of potassium ion by flame test, where species containing potassium ion will show a lilac colour flame, but this is a physical test. A lot of books' questions asked me to suggest a 'chemical test' for potassium ion but give 'flame test' in their answer key...
C is the chemical symbol for which element with the atomic number 6? What does the atomic number of an element represent? What is the symbol for potassium on the periodic table? What is the chemical element xenon? What is the chemical element tungsten also called?
Adopted as a free-standing anode (~ 7 mg·cm2) for potassium ion battery, the as-achieved CNCG delivers a high reversible specific capacity of 317.7 mAh·g1 at a current density of 50 mA·g1 and admirable cycle stability (208.4 mAh·g1 at 50 mA·g1 after 500 cycles). The highly ...
Even though it may be rare, some people may have extremely bad and occasionally deadly side effects when taking Potassium Acetate.
[Lab. Govt. Chemist 1965]. A mixture of powdered zinc and an oxidizing agent such as potassium chlorate or powdered sulfur can be exploded by percussion. Zinc burns in moist chlorine. A mixture of zinc and carbon disulfide reacts with incandescence. Zinc powder reacts explosively when heated ...

On the other hand, the potassium cation triggered the guanosine unit DNA sequences through self-assembled G-quadruplex interactions. A second similar DC strategy was also studied using complementary sequences of a specific oligonucleotide inducing the formation of base pairing using about 10 nucleobases...
resistivity 1.71 microhm-cm at 25°C; Poisson's ratio 0.33; melts at 1,083°C; vaporizes at 2,567°C; insoluble in water; dissolves in nitric acid and hot sulfuric acid; slightly soluble in hydrochloric acid; also soluble in ammonium hydroxide, ammonium carbonate and potassium cyanide ...
ion exchange resin, the iodine-containing solution desorbed with sodium sulfite precipitates iodine by adding potassium chlorate and sulfuric acid. Heat the crude iodine to 150 ℃ or more, add concentrated sulfuric acid for melt refining. Iodine is ready after being cooled, crystallized and crushed...
