If the cobalt chloride paper turns colour from blue to pink, water (moisture) is present.
When cobalt II chloride paper turns pink, this means that it has detected water. :-)
mostly 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.
Imagine a sparkler... Cobalt Chloride sends off millions of tiny, yellow sparks that shoot upward with the flame. Do not get to close when doing a flame test
The cobalt chloride test paper would turn from blue to pink when exposed to ethanol. This is because ethanol dehydrates the cobalt chloride, causing a change in color.
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.
When cobalt II chloride paper turns pink, this means that it has detected water. :-)
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.
Cobalt chloride paper turns from blue to pink in the presence of water. Limewater turns cloudy in the presence of carbon dioxide.
mostly blue.
Water turns blue cobalt chloride pink and it has a boiling point of 100 C.

The cobalt chloride paper test is a simple test used to detect the presence of moisture in a given sample. When it comes into contact with water, cobalt chloride changes color from blue to pink. This paper test is commonly used in science experiments and as a qualitative indicator for water in various substances.
The cobalt chloride test paper would turn from blue to pink when exposed to ethanol. This is because ethanol dehydrates the cobalt chloride, causing a change in color.
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.
Pink cobalt chloride paper will turn blue when exposed to water. Cobalt chloride is a chemical compound that changes color based on the amount of water present, with pink indicating a dry condition and blue indicating the presence of water.
