What change in colour is observed when silver chloride is left exposed to sunlight state the type of chemical reaction in this change.?
Silver chloride changes from white to gray or purple when exposed to sunlight, due to the decomposition of silver chloride into elemental silver and chlorine gas. This is a photochemical reaction, where light energy initiates the reaction.
Which one is a chemical change-eletrolysis of water or sodium chloride exposed in sunlight?
The electrolysis of water is a chemical change because it breaks down water molecules into hydrogen and oxygen gas. On the other hand, sodium chloride exposed to sunlight is a physical change as it may undergo phase changes, but the chemical composition remains the same.
What type of reaction takes place when silver bromide is exposed to sunlight?
Photodecomposition reaction occurs when silver bromide is exposed to sunlight. The sunlight causes the silver bromide to decompose into silver and bromine atoms, leading to a color change from white to grey or black.
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 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.

What change in color is observed when silver chloride is left exposed to sunlight. What type of chemical reaction is this?
This is a photochemical reaction of decomposition: silver (black) is released.

What is the independent variable in a rate of growth of a plant exposed to sunlight and one that is not?
Whether or not the plant is exposed to sunlight. Independent variables are manipulated by the experimentor, dependent variables react to the change in the independent variable.
Is a UV bead the same as a regular bead?
No. A UV Bead will change color when exposed to sunlight.
What type of reaction takes place when silver bromide is exposed to sunlight?
Photodecomposition reaction occurs when silver bromide is exposed to sunlight. The sunlight causes the silver bromide to decompose into silver and bromine atoms, leading to a color change from white to grey or black.

Why does the color of AGCL change?
The color of silver chloride (AgCl) can change due to various factors such as exposure to light, impurities present, or changes in temperature. When AgCl is exposed to light, a photochemical reaction can occur, leading to a change in color from white to gray or pale yellow. Other impurities or reactions can also lead to color changes in silver chloride.
How does a UV activated shirt change color in response to sunlight exposure?
A UV activated shirt changes color in response to sunlight exposure because the special dye in the fabric reacts to ultraviolet (UV) light. When the shirt is exposed to sunlight, the UV rays cause the dye molecules to change structure, which results in a color change. This process is reversible, meaning the shirt will return to its original color when no longer exposed to UV light.
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.
How does cobalt chloride change with water?
Cobalt chloride can form different hydrate compounds when exposed to water, such as pink cobalt chloride hexahydrate or blue cobalt chloride dihydrate. These hydrates have different colors due to their varying water content.
