It is because carrots contain water and there must be moisture present for this reaction to happen.

What color does cobalt burn?
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
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.
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 the color of dry cobalt chloride paper?
mostly blue.
What colour does pink cobalt chloride paper turn in water?
BLUE
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.

Cobalt chloride paper test?
water or water vapour will turn the blue cobalt chloride paper pink

What would be the color of cobalt chloride test paper be with a drop of ethanol?
Blue.
Which liquid that boils at 104 degrees turns blue cobalt chloride pink?
The anhydrous cobalt chloride (blue) become purple after the contact with water and transformation in the CoCl2.6H2O.But the boiling point of water is 100 oC.
What is cobalt chloride paper and what it is used for?
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.
What is the purpose of cobalt Chloride?
Cobalt chloride is mainly used to measure the moisture absorption in de-humidification processes. This solid product is originally blue and turns to pink when it becomes completely saturated with moisture.
