Is adding water to heated copper sulfate crystals chemical or physical?
Adding water to heated copper sulfate crystals is a chemical change. When water is added to heated copper sulfate crystals, the copper sulfate undergoes a chemical reaction where it dissolves in the water to form a solution. This is a chemical change because the chemical composition of the copper sulfate is altered during the process.
Why is heating copper sulfate a chemical change?
Heating copper sulfate causes a chemical change because it leads to the compound decomposing into different substances, namely copper oxide and sulfur dioxide. This change alters the chemical composition and properties of the original compound, indicating a chemical reaction has occurred.
Is copper sulfate a physical or chemical change when heated?
Thermal decomposition and loss of water are chemical changes.
Does heating copper II sulfate produce a chemical change or physical change?
Heating Copper Sulfate gently drives off the water of crystallization leaving an amorphous white powder. This is purely a physical reaction. Heating this powder strongly will cause a chemical reaction liberating sulfur dioxide and oxygen, leaving black copper(II)oxide: 2CuSO4 >2CuO + 2SO2 + O2
Is heating copper sulfate and water a chemical change?
Yes, it undergoes the clues that indicate that a chemical change has happened.new colour appearsheat or light is producedbubbles or gas are formeda solid forms into a liquidchange is hard or impossible to reverseFour out of the five are met. A solid does not turn into a liquid during this process.
Why is heating cupric sulfate a chemical change?
It is not.
Is adding water to heated copper sulfate crystals chemical or physical?
Adding water to heated copper sulfate crystals is a chemical change. When water is added to heated copper sulfate crystals, the copper sulfate undergoes a chemical reaction where it dissolves in the water to form a solution. This is a chemical change because the chemical composition of the copper sulfate is altered during the process.
Is the heating of iodine crystals a chemical or physical change?
It is a physical change (sublimation).
Why is heating copper sulfate a chemical change?
Heating copper sulfate causes a chemical change because it leads to the compound decomposing into different substances, namely copper oxide and sulfur dioxide. This change alters the chemical composition and properties of the original compound, indicating a chemical reaction has occurred.
Is heating potassium chloride crystals a physical or chemical change?
Heating potassium chloride crystals is a physical change because it only affects the physical state of the substance (solid to liquid) without changing its chemical composition.
Is heating copper sulfate pentahydrate a chemical reaction?
No, it is not a chemical reaction. The added heat only drives the water molecules out of the crystal structure. No bonds are made or broken. Actually, it is a chemical change, because there are bonds between the water and CuSO4. by heating, these bonds are broken, there is a color change not coming from the reactant.
Is copper sulfate a physical or chemical change when heated?

Why colour of copper sulphate crystals changes on heating?
The color change of copper sulfate crystals on heating is due to the loss of water molecules from the crystal lattice. The blue color of hydrated copper sulfate is due to the presence of water molecules within the crystal structure. When heated, these water molecules are driven off, leading to a white color (anhydrous copper sulfate) as the crystal becomes dehydrated.
Why crystals of copper sulphate turn white on heating?
When crystals of copper sulfate are heated, the water of hydration within the crystals is driven off, and the anhydrous copper sulfate formed is white in color. This change in color is due to the removal of water molecules, which alters the crystal structure of the compound and causes it to appear white instead of blue.
Is Heating a hydrous salt to obtain an anhydrous salt a chemical or physical change?
if you mean epsom salts (magnesium sulfate) then heating it will result in a decomposition reaction, where magnesium oxide (s) and sulfur trioxide (g) is formed. The decomposition reaction is therefore a chemical change.
