When copper sulfate salt and water are mixed is it a chemical or physical change?
When copper sulfate salt is mixed with water, it undergoes a physical change. The salt dissolves in the water, resulting in a homogeneous solution, but the chemical composition of the copper sulfate remains unchanged. This process is reversible, as the water can be evaporated to retrieve the original salt.
Is hammered copper a physical change?
Yes, hammered copper is a physical change. When copper is hammered, its shape and size change, but its chemical composition remains the same.
Is copper one pounded into sheets is a chemical or physical change?
This is a physical change.
What formula is copper sulfate?
The chemical formula for copper sulfate is CuSO4.
How can you change blue copper sulfate to white copper sulfate?
To change blue copper sulfate to white copper sulfate, you can heat the blue copper sulfate to drive off the water molecules and get anhydrous white copper sulfate. This process is known as dehydration. Be cautious when heating copper sulfate as it can release toxic fumes.
Is copper sulphate a physical change or chemical?
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
Is copper sulphate a physical change?
Copper sulfate dissolving in water is a physical change because the chemical composition of copper sulfate remains the same. Physical changes do not alter the chemical structure of a substance.
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 copper sulfate a physical or chemical change when heated?
Thermal decomposition and loss of water are chemical changes.
When copper sulfate mixed with sodium hydroxide is a form of physical change or chemical change?
The reaction between copper sulfate and sodium hydroxide is a chemical change, as new substances are formed with different chemical properties from the original substances. The blue copper sulfate solution reacts with the colorless sodium hydroxide solution to form a blue precipitate of copper hydroxide and sodium sulfate solution.
Copper sulfate and sodium carbonate physical or chemical change?
When copper sulfate and sodium carbonate are mixed together, a chemical reaction occurs. This reaction forms copper carbonate, a new substance with different properties than the reactants. Therefore, the mixing of copper sulfate and sodium carbonate is a chemical change.
Why should copper sulfate dissolution be regarded as a chemical change?
Dissolution of Copper sulphate in water is a Physical Change... It cannot be regarded as a Chemical Change.
What kind of change is grinding copper sulfate pentahydrate?
Grinding copper sulfate pentahydrate is a physical change because no new substances are formed during the process. The copper sulfate remains the same chemical compound, but its physical state is altered as it is broken down into smaller particles.
When copper sulfate salt and water are mixed is it a chemical or physical change?
When copper sulfate salt is mixed with water, it undergoes a physical change. The salt dissolves in the water, resulting in a homogeneous solution, but the chemical composition of the copper sulfate remains unchanged. This process is reversible, as the water can be evaporated to retrieve the original salt.
Is crystallization of copper sulphate a physical change?
Yes, crystallization of copper sulfate is considered a physical change. This process involves the copper sulfate molecules arranging themselves into a specific crystal lattice structure without changing their chemical composition. Therefore, it does not involve any chemical reactions.
Is a sodium carbonate and copper sulfate mixture a chemical change?
No, mixing sodium carbonate and copper sulfate is a physical change as the substances retain their chemical identities. A chemical change would involve a reaction where new substances are formed.
How do you conclude of these reactions between copper sulfate and water?
When copper sulfate is added to water, it dissolves to form a blue solution of copper ions and sulfate ions. The dissolution process is a physical change where the copper sulfate molecules are surrounded by water molecules. This reaction does not involve any chemical bond formation or breaking, so it is classified as a physical change.
