If water evaporates then cobalt chloride near or above the water will do what?
Reacts with the cobalt chloride and makes hydrochloride and cobalt
Is cobalt chloride the same with cobalt dichloride?
Cobalt (I) chloride = Cobalt monochloride = CoCl Cobalt (II) chloride = Cobalt dichloride = CoCl2 Cobalt (III) chloride = Cobalt trichloride = CoCl3
Cobalt chloride will give a positive test for?
Cobalt chloride is used to test for the presence of water. If there is no water present it is blue, if water is present it goes pink.
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.
What is CuCl3?
if there's that dot in the between the chloride and the water molecule: cobalt (II) chloride hexahydrate.Cobalt(II) Chloride Hexahydrate

C0cl2 and water is it a physical or chemical change?
The hydration of anhydrous cobalt chloride is a chemical change.
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.
If water evaporates then cobalt chloride near or above the water will turn what color?
The anhydrous cobalt chloride is blue.
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 will give a positive test for?
Cobalt chloride is used to test for the presence of water. If there is no water present it is blue, if water is present it goes 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.
What is detected when cobalt chloride paper turns pink?
When cobalt II chloride paper turns pink, this means that it has detected water. :-)
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.
