Why does anhydrous calcium chloride turn wet on exposure to air?
Wiki User
∙ 11y ago
That is because it is hygroscopic in nature and it absorbs moisture from air. If exposed to open air, it tends to become liquid. That is why, it is often called as deliquescent substance (deliquescent substances are substances which absorbs an excessive amount of water from its surroundings/ atmosphere that it forms a liquid.)

What colour does calcium chloride turn into when burnt?

Does phenol red mixed with calcium chloride and baking soda turn out to be a exothermic or endothermic?
it results in a exothermic reaction

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 anhydrous copper sulphate?
The difference is that anhydrous copper(II) sulfate has no water of crystallisation. The anhydrous variant is a white solid while the hydrated variant is blue. Also, the chemical formula for hydrated copper(II) sulfate (or copper sulfate pentahydrate) is CuSO4.5H2O while that of the anhydrous one is CuSO4.
If water evaporates then cobalt chloride near or above the water will turn what color?
The anhydrous cobalt chloride is blue.
What colour does calcium chloride turn into when burnt?
brick red It is not a burning but a heating process.
How could you tell if an unkown substance is sodium chloride or calcium carbonate?
Add dilute hydrochloric acid to both. There will be no reaction with the sodium chloride but the calcium chloride will effervesce and give off carbon dioxide which will turn lime-water milky.
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 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.
Does phenol red mixed with calcium chloride and baking soda turn out to be a exothermic or endothermic?
it results in a exothermic reaction
What happens when calcium chloride sodium bicarbonate and phenol red solution are mixed together?
Calcium Chloride and Sodium Bicarbonate turn pink, then turn yellow due to carbonic acid that is created. the mixture turns hot and gas is, about 10 seconds later the mixture stops producing gas and turns cold.

How do you turn magnesium chloride into a compound?
Magnesium chloride is already a compound.
What is the reaction between cupric chloride and copper?
If you add Copper in Cupric Chloride at the time of reaction, it will turn into Cuprous Chloride. But it will again turn into Cupric Chloride if you continue the reaction. This is actually a Exo-Thermic reaction.
What is anhydrous copper sulphate?
