exhaled air contains water vapour, when water comes in contact with cobalt chloride paper, the blue paper turns pink.
beacause when it is placed on the plant the water in the leaf turnes the coblt chloride paper from blue to pink
because of the presence of water in the liquid
When cobalt II chloride paper turns pink, this means that it has detected water. :-)
If cobalt chloride paper turns yellow, that just means it your salt contains a transition metal.
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.
No. Cobalt chloride paper is used for testing the appearance of wate. Whilst pH paper is used for testing the pH value of a particular chemical/solution.
mostly blue.
The colour of cobalt chloride paper is BLUE when NO WATER is present.When WATER is present it is PINK.

Cobalt chloride paper is used to study rate of transpiration through the upper and lower surface of leaf.The upper surface of leaf has less number of stomata so more time will be taken to change from blue to pink by cobalt chloride paper; while the lower surface of leaf has more number of stomata so less time will be taken to change from blue to pink by cobalt chloride paper. This is because the fact that the transpiration rate is higher when stomata are more in number and vice versa.

By using cobalt chloride paper. The acidity of the water would change the color of the paper due to the Ph balance.

Shiizzz
mostly blue.
in the movie it is real but..... it is not real
pink
