Despite that potassium chlorate catches on fire when it gets heated in the open, if you put it in a test tube and heat that, instead of burning it will melt into molten form, and this stage of potassium chlorate is extremely reactive, any contact with anything combustible like sugar would cause combustion of it. This is the basis for the famous gummy bear and potassium chlorate experiment. The sugar in the gummy bear would combust on contact with the molten potassium chlorate, resulting in an violent reaction.
One way to separate potassium chloride from aqueous potassium chloride is through evaporation. By heating the aqueous solution, the water will evaporate, leaving behind solid potassium chloride. Another method is through precipitation by adding a chemical that reacts with potassium ions to form a solid precipitate of potassium chloride that can then be filtered out from the solution.
You can separate solid potassium chloride from aqueous potassium chloride by processes like evaporation or crystallization. Simply heating the aqueous solution can evaporate the water and leave behind solid potassium chloride. Alternatively, you can allow the solution to cool slowly, causing potassium chloride crystals to form and separate from the liquid.
Potassium dichromate can be separated from water by a process of crystallization. This technique involves heating the potassium dichromate solution to a temperature just below the boiling point. As the solution cools, the potassium dichromate begins to crystallize out of the solution, allowing it to be filtered out and collected. The remaining liquid can then be discarded.
The difference between potassium nitrate and potassium sulphate is that the potassium nitrate is superior to potassium sulphate. The potassium nitrate has high solubility while the potassium sulphate has moderate solubility.
One way is to react hot aqeous solution of potassium hydroxide (KOH) with sulphur (S). The products will be K2S3, K2S2O3 (potassium thiosulphate) and H2O. Answer by aditya rajesh, 8th student at millennium school in dubai.
No. Potassium metal is to reactive and expensive for everyday use.
yes KClO3 + heat --> KCl + O2
2KClO3 ----> 2KCl + 3O2
Heating anything to a visible change is ALWAYS a chemical change

Heating potassium bicarbonate is a chemical change because it causes a decomposition reaction. This results in the formation of new substances (potassium carbonate, water, and carbon dioxide) that have different chemical properties than the original compound.

The nitrogen dioxide (NO2) is released.
Potassium dichromate can be separated from water by a process of crystallization. This technique involves heating the potassium dichromate solution to a temperature just below the boiling point. As the solution cools, the potassium dichromate begins to crystallize out of the solution, allowing it to be filtered out and collected. The remaining liquid can then be discarded.
When heating potassium chlorate, it decomposes to form potassium chloride and oxygen gas. The reaction is catalyzed by heat and may be vigorous, resulting in the release of oxygen gas and leaving behind a residue of potassium chloride.
You do NOT produce oxygen from potassium chloride(KCl), There are no oxygen atoms present in the chloride, so you cannot produce oxygen. However, potassium chlorate (KClO3), Note the spelling and the chemical formula, Oxygen can be produced as the potassium chlorate decomposes to liberate oxygen.
