What else can I help you with?
What would you see on Cobalt Chloride paper if water vapour was present?
If water vapor is present, cobalt chloride paper would change color from blue to pink. Cobalt chloride is a chemical indicator that is blue when dry and turns pink when exposed to moisture.
What is the colour of cobalt react with ammonia?
Probable you think to hexaamminocobalt chloride: the color is orange.
Which terms describe the pink cobalt chloride and the reaction?
Pink cobalt chloride is described as a hygroscopic compound, meaning it readily absorbs moisture from the air. In its anhydrous form, it appears blue, but when it absorbs water, it turns pink, indicating a hydration reaction where water molecules coordinate with the cobalt ions. This color change can be used as a simple indicator for humidity levels in the environment. Overall, the reaction involves the transition between cobalt(II) chloride and its hydrated form, cobalt(II) chloride hexahydrate.
Which soluble salts are blue?
Copper (II) sulfate and cobalt (II) chloride are examples of soluble salts that are blue in color.
What happened when you put blue cobalt chloride paper on to a mirror?
When blue cobalt chloride paper comes into contact with a mirror, it may change color due to moisture. Cobalt chloride is hygroscopic, meaning it absorbs water vapor from the air. If the mirror is cool enough, condensation can form on its surface, causing the blue paper to turn pink as it absorbs the moisture. This reaction demonstrates the paper's ability to indicate humidity levels.
If water evaporates then cobalt chloride near or above the water will do what?
If water evaporates, cobalt chloride near or above the water will turn from blue to pink due to the change in humidity levels. Cobalt chloride is a common indicator for moisture because it changes color in response to water vapor in the air.
What color will a cobalt chloride paper turn into when there is water vapor?
A cobalt chloride paper will turn pink when exposed to water vapor. This color change is due to the cobalt chloride reacting with the water vapor to form pink cobalt chloride hexahydrate.
What is the color of dry cobalt chloride paper?
mostly blue.
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.
This transition metal is especially known for the deep blue color?
Cobalt !
What will be the colour change of cobalt chloride paper if water present?
Cobalt chloride paper changes color from blue to pink when exposed to water due to the absorption of water molecules into the paper, which alters the chemical structure of the cobalt chloride.
What would happen if you breathe out on cobalt chloride paper?
If you breathe out on cobalt chloride paper, the paper will turn pink due to the presence of moisture (water vapor) in your breath. Cobalt chloride paper is used as a moisture indicator and changes color in the presence of water.
What would you see on Cobalt Chloride paper if water vapour was present?
If water vapor is present, cobalt chloride paper would change color from blue to pink. Cobalt chloride is a chemical indicator that is blue when dry and turns pink when exposed to moisture.
What would turn cobalt chloride paper yellow?
Cobalt chloride paper turns yellow when exposed to moisture or high humidity levels. This change in color indicates that the paper has absorbed water and undergone hydration, resulting in the yellow color.
What is the colour of cobalt react with ammonia?
Probable you think to hexaamminocobalt chloride: the color is orange.
What would you see if excess cobalt oxide is warmed with hydrochloric acid?
When excess cobalt oxide is warmed with hydrochloric acid, the cobalt oxide will react with the acid to form cobalt chloride, water, and chlorine gas. The resulting solution may be pink due to the presence of cobalt ions, which are often a characteristic color of cobalt compounds.
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
