(phenolphthalein indicator). The solution was treated with an equimolar amount of iodine inpotassiumiodide solution until a yellow colour appeared. Free iodine was removed by means ofsodiumthiosulfate solution. The precipitate was filtered off and crystallised from ethanol to yield the disulfide in...
Potassium fluoride (6.4 g, 0.11 mol) and cuprous iodide (21 g, 0.11 mol) were thoroughly mixed and flame heated under gentle shaking and at reduced pressure (1 Torr) during some 30 min until a greenish colour appeared. 2-Iodopyridine (21 g, 0.10 mol), (trifluoromethyl)trimethylsilane (15...

The solution loses its pink colour after all the permanganate ions are used up in the chemical reaction. It is meant by the end of the reaction, and thus potassium permanganate is known as self-indicator as it acts as an indicator besides being one of the reactants....
Potassium reacts rapidly and intensely with water, forming a colourless basic potassium hydroxide solution andhydrogengas, according to the following reaction mechanism: 2K (s) + 2H2O (l) -> 2KOH (aq) + H2(g) This is an exothermal reaction and potassium is heated to such an extend that...
It also can be formed by oxidation of potassium amalgam with dry air or oxygen.) The metal is also used as analloywithsodiumas a liquid metallic heat-transfer medium. Potassium reacts very vigorously with water, liberatinghydrogen(which ignites) and forming a solution of potassium hydroxide, ...
