What is the colour of the compound formed when potassium reacts with chlorine?
The compound formed when potassium reacts with chlorine is potassium chloride, which is a white crystalline solid.
Does potassium change a different colour when mixed with water?
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.
Why is methylcyclopentanol does not change the colour of potassium permanganate?
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.
Name the following binary compound K2Cr2O7?
The chemical name is, potassium dichromate. It is orange in colour. Dichromate ion gives colour for this compound.
What is the colour of potassium superoxide?
Potassium superoxide is yellow in color.
What is the colour of the compound formed when potassium reacts with chlorine?
The compound formed when potassium reacts with chlorine is potassium chloride, which is a white crystalline solid.
what is the colour change observed when Potassium manganate reacts with ethanol?
Purple colour
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-
When chlorine is added to potassium iodide solution the colour changes from colourless to a dark reddy brown why does this happen?
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.
What is the colour of chlorine?
the colour of Chlorine is green.

What colour change will occur when potassium dichromate reacts with ethanol?
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. :)

What is the colour of potassium superoxide?
Potassium superoxide is yellow in color.
What colour does universal indicator change to if chlorine water is added?
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.
How do you measure chlorine by using chlorotex?
Chlorotex has 4 colours on d back side of its label..according to the colour you get the readings of 0.2, 0.4, 0.6 and 1 ppm when d chemical is mixed with water it changes its colour according to d chlorine content and later comparing the changed colour with the colour on d back side of d bottle gives the amount of chlorine present in the water :) :)
