What would be the color of cobalt chloride test paper be with a drop of ethanol?

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.


Is cobalt chloride paper the same thing as pH paper?

No, cobalt chloride paper and pH paper are not the same. Cobalt chloride paper is used to test for the presence of water, while pH paper is used to test the acidity or alkalinity of a solution by measuring its pH level.


What color flame test does cobalt and chromium give?

Cobalt gives a blue flame test while chromium gives a green flame test.


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


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.

Why does the cobalt chloride test paper turn pink when wet?

Cobalt chloride test paper is blue when dry because of the presence of hydrated cobalt chloride. When it comes into contact with water, the chloride ions displace the water molecules from the cobalt chloride structure, resulting in the formation of a pink-colored hexa-aqua complex of cobalt chloride.

Why mercuric chloride does not give chromyl chloride test?

Mercuric chloride does not give the chromyl chloride test because it lacks the ability to form a stable complex with chromyl chloride. The test relies on the formation of a complex between the reagent chromyl chloride and the compound being tested, leading to a characteristic color change which is not observed with mercuric chloride.
