What is the colour of potassium bromide dissolved in water?
Bromine is solution is orange/red depending on how dilute it is. Potassium permanganate solutions are purple.
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.
What are some physical characteristice of potassium chromate?
It is yellow in colour. Has good solubility in water. Its colour changes from yellow to orange if put into an acid
What is the color of Potassium oxide?
When freshly cut it is silvery in colour but it quickly tarnished as it reacts with oxygen in the air. all alkali metals give characteristic flame colour wich are used to identify them potassium has the colour LILAC
What are the examples of diffusion in liquids in the house?
Adding water to a cordial is diffusion - the movement of the cordial from an area of high concentration to an area of low concentration ie dilution is an example of diffusion in liquids - also a crystal of potassium permanganate in water, watch the colour spread (diffuse out) as the crystal dissolves
Why does the purple colour spread when a crystal of potassium permanganate is placed in water?
A water solution of potassium permanganate is formed.
What colour flame test do sodium sulphate and potassium chloride give?

Why do potassium oxide and potassium chloride give off the same colour of light in a flame test?
The color is from the potassium !
Is potassium cloride dissolving in water a chemical change?
Potassium metal does not dissolve in water, it is so reactive that it rips water molecules apart releasing hydrogen gas and combining with the remaining hydroxyl group to form potassium hydroxide (potash lye) which then dissolves in the water. This chemical reaction releases so much heat that it ignites the hydrogen gas that was emitted which produces water vapor/steam and a light purple flame (caused by excited potassium ions).
what is the colour change observed when Potassium manganate reacts with ethanol?
