The compound formed when potassium reacts with chlorine is potassium chloride, which is a white crystalline solid.
Potassium metal does not change color when mixed with water. However, it reacts vigorously with water, producing hydrogen gas and forming potassium hydroxide. The reaction is exothermic, releasing a significant amount of heat. This reaction is often used to demonstrate the reactivity of alkali metals with water.
Methylcyclopentanol does not change the color of potassium permanganate because it is not easily oxidizable by the permanganate ion. The structure of methylcyclopentanol does not provide the necessary functional groups or carbon-hydrogen bonds that can be readily oxidized by potassium permanganate.
The chemical name is, potassium dichromate. It is orange in colour. Dichromate ion gives colour for this compound.
Potassium superoxide is yellow in color.

Purple colour
Chlorine is a stronger oxidizer than elemental Bromine. So, when yellowish chlorine gas is bubbled through the Bromide solution, a red colour is formed which is Bromine. Chlorine oxidizes Bromide ions to elemental Bromine while itself is reduced to Chloride ions. So, the total reaction is: Cl2 + Br- ----> Br2 + Cl-
The dark red-brown color change occurs because the chlorine oxidizes iodide ions to form iodine, which reacts with excess iodide ions to form triiodide ions. These triiodide ions absorb light in the visible range, resulting in the dark red-brown color observed in the solution.
the colour of Chlorine is green.

Potassium dichromate is orange and when it reacts with ethanol which is a primary alcohol it is going to oxidise it to form aldehyde which is colorless. so the color change is from Orange to Colorless. :)
Potassium superoxide is yellow in color.
chlorine does not have a colour
Universal indicator will change to a bleaching effect color (yellow or yellow-green) when chlorine water is added due to the presence of hypochlorous acid.
