It turns it purple with water.

If water evaporates, cobalt chloride near or above the water will turn from blue to pink due to the change in humidity levels. Cobalt chloride is a common indicator for moisture because it changes color in response to water vapor in the air.
Cobalt chloride paper changes color from blue to pink when exposed to water due to the absorption of water molecules into the paper, which alters the chemical structure of the cobalt chloride.
Yes, cobalt chloride and cobalt dichloride refer to the same compound. Cobalt chloride is also known as cobalt(II) chloride or cobalt dichloride, as it consists of one cobalt ion and two chloride ions.
Anhydrous cobalt chloride will absorb water and form hydrated cobalt chloride. This process is reversible, with the hydrated cobalt chloride releasing water vapor to revert back to anhydrous cobalt chloride when heated.
When cobalt II chloride paper turns pink, this means that it has detected water. :-)
A cobalt chloride paper will turn pink when exposed to water vapor. This color change is due to the cobalt chloride reacting with the water vapor to form pink cobalt chloride hexahydrate.

If water vapor is present, cobalt chloride paper would change color from blue to pink. Cobalt chloride is a chemical indicator that is blue when dry and turns pink when exposed to moisture.
The anhydrous cobalt chloride is blue.
Cobalt chloride test paper is blue when dry because of the presence of hydrated cobalt chloride. When it comes into contact with water, the chloride ions displace the water molecules from the cobalt chloride structure, resulting in the formation of a pink-colored hexa-aqua complex of cobalt chloride.
Anhydrous cobalt chloride will absorb water and form hydrated cobalt chloride. This process is reversible, with the hydrated cobalt chloride releasing water vapor to revert back to anhydrous cobalt chloride when heated.
Cobalt (II) chloride dihydrated (purple colour) and with more water Cobalt (II) chloride hexahydrated (pink colour) .
When cobalt II chloride paper turns pink, this means that it has detected water. :-)
Gas molecules interact with the cobalt chloride paper, causing a chemical reaction that results in a change in the structure of the cobalt chloride molecule. This change in structure alters the way the molecule absorbs and reflects light, leading to the paper appearing pink instead of blue.
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.
