When potassium metal and water are mixed, a chemical reaction occurs. This exothermic reaction produces hydrogen gas and potassium hydroxide, which dissolves in the remaining water. This reaction can be vigorous and produce light, heat and sound.
When you put potassium permanganate into water, it changes to a deep purple or violet color.
When hydrochloric acid and potassium hydroxide react together in water, they form potassium chloride (KCl) and water (H2O) as products.
A reaction would occur between bromine water and potassium astatide, resulting in the displacement of bromine by astatine. This would lead to the formation of potassium bromide and astatine would be released. The solution would likely change color as astatine is a highly reactive halogen with distinctive coloration.
i have no idea i was searching for it...i'm just playing around.
it falls to the bottem of the water
When potassium is added to water, it reacts vigorously, producing hydrogen gas and a lot of heat. The reaction is highly exothermic and can result in the ignition of the hydrogen gas, producing a flame. The reaction between potassium and water is so violent that it can cause the potassium metal to explode.
Water (H2O) is a product of the reaction between hydrochloric acid (HCl) and potassium hydroxide (KOH), along with potassium chloride (KCl).
If potassium permanganate solution is dropped into water, it will dissolve and create a purple or pink solution. Potassium permanganate is a strong oxidizing agent and can be used for various applications such as disinfection and water treatment.
If you think to potassium "permanganate" this compound can be decomposed under the influence of UV radiations.
Pure Potassium (K) will catch fire and may explode upon contact with water or very humid air.
The entropy is changed.
When potassium permanganate is added to water, the water changes color to a pink or purple hue. This is because potassium permanganate is a strong oxidizing agent that reacts with organic compounds present in the water, causing the color change.
