Why gas turns cobalt chloride paper from blue to pink?
It is because carrots contain water and there must be moisture present for this reaction to happen.
What is detected when cobalt chloride paper turns pink?
When cobalt II chloride paper turns pink, this means that it has detected water. :-)
What is cobalt chloride paper in simple terms?
Cobalt chloride paper is absorbent paper which has been soaked in cobalt chloride solution and allowed to dry. It is a convenient way to use cobalt chloride as a test for the presence of water. When cobalt chloride is anhydrous, that is completely without water, it is blue, but when there is water present, either in solution or in the solid, it is pink. To use cobalt chloride paper it is heated to drive off the water present, until it turns blue. You then dip it into the liquid you want to test. Water,or any liquid such as milk which contains water, will turn the paper pink (it may look white if there's not much cobalt chloride on it). Other liquids, e.g. gasoline, will have no effect.
Why does cobalt chloride paper change from blue to pink when it is placed on a leaf or a plant?
exhaled air contains water vapour, when water comes in contact with cobalt chloride paper, the blue paper turns pink.
In the presence of water what happens to anhydrous cobalt chloride?
The colour become initially purple and after (with more humidity) pink.
What color will a cobalt chloride paper turn into when there is water vapor?
The colour of cobalt chloride paper is BLUE when NO WATER is present.When WATER is present it is PINK.
What is formed when Cobalt chloride is tested with steam?
Cobalt (II) chloride dihydrated (purple colour) and with more water Cobalt (II) chloride hexahydrated (pink colour) .

Cobalt chloride paper test?
water or water vapour will turn the blue cobalt chloride paper pink

How is cobalt chloride used to find out if water is present?
The cobalt chloride changes colour in the presence of water because of the different amount of protons and electrons that are present.
Will damp cobalt chloride turn back blue once dried?
Solid Cobalt chloride crystals are pink when hydrated with water. If you heat the crystal, the water of crystallisation in the crystals will evaporate, leaving you with solid anhydrous cobalt chloride crystals which are blue in colour.
What would you see on Cobalt Chloride paper if water vapour was present?
Doubt it

If water evaporates then cobalt chloride near or above the water will do what?
Reacts with the cobalt chloride and makes hydrochloride and cobalt
