Is copper sulfate a pure substance?
Yes, copper sulfate is considered a pure substance because it has a definite and uniform composition of copper, sulfur, and oxygen in a fixed ratio. It can be represented by a chemical formula (CuSO4) and is not a mixture of different substances.
Is copper when it turns green in the air a chemical change?
The green color on copper when it oxidizes in the air is a physical change, not a chemical change. The process is primarily due to the formation of a layer of copper oxide on the surface of the copper, which alters the appearance without changing the chemical composition of the copper itself.
Which substance has the formula CuO?
Copper (II) oxide, also known as cupric oxide, has the chemical formula CuO. It is a black solid and is commonly used as a pigment in ceramics and glass.
What is copper carbonate formula?
It depends ~ if it's copper(I), then the formula is Cu2CO3, but if it's copper(II), the the formula is CuCO3
Is copper sulfate a element?
