pink
Anhydrous cobalt chloride paper is blue, as it is in the presence of water or any sort of moisture it starts to turn pink.so if you are using it keep out of air until your ready to use it and dont touch it with ypur hands because the moisture on your fingers woulde change the outcome of your lab. :) ....so in other words its used to test moisture :P Hope i helped !
There are a great number of tests that can be performed on water to asses its chemical compositions. Typically, metal analysis is perfomed by AAS, pH, conductivity, chemical oxygen demand. A more specific question would allow for a more detailed answer.
Cobalt Chloride paper may be purchased online however it was recently found to be a carcinogen. A safer test for H2O is Anhydrous Copper Sulfate. It is made by heating copper sulfate in a test tube over a Bunsen burner until it goes white. It then turns blue in the presence of H2O. I am not aware of an Anhydrous Copper Sulfate paper, however one may exist.
no answer..BOO!
You can do the pH test and if it is 7 it should be water but something might have dissolved in it. So boil it at 100 degrees C and freeze it at 0 degrees C and if nothing is dissolved in it that should work.
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.
water or water vapour will turn the blue cobalt chloride paper pink
Cobalt chloride is used to test for the presence of water. If there is no water present it is blue, if water is present it goes pink.
Blue.
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

Testing with indicator paperstrip: Iodide-Starch gets blue

water turns blue cabolt chloride pink.
