Does potassium change a different colour when mixed with water?
It can be argued it does as Potassium is a silvery gray metal. When reacted with water it produces colorless Potassium Hydroxide and colorless hydrogen gas.
Why does acidified potassium permanganate turn from purple to colorless when added to an alkene?
The purple colour is the Manganese in oxidation state '+7'. This oxidation state is reduced to '+2' ,which is pale green/colourless, when reacted with the alkene. Hence the change of colour.

When chlorine is added to potassium iodide solution the colour changes from colourless to a dark reddy brown why does this happen?
Chlorine displaces Potassium Iodide to liberate aqueous I2(brown colour). Hence the solution turns brown.

Why does the color of aqueous potassium bromide change when chlorine gas is bubbled into it?
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-
