Why is decantation considered a chemical change?

Answer 1

Decantation is not considered a chemical change as it is a physical change.

This is so because no chemical bonds are broken/formed in the process...it's merely a process of gravity where heavier components of a mixture that are not dissolved fall to the bottom.

Answer 2

Decantation is not considered a chemical change. It is a physical process used to separate mixtures based on the differences in densities of the substances involved. In decantation, the components remain chemically unchanged.

Answer 3

Decanting means pouring something out of a container. It is not a change, physical or chemical. Chemical changes MAY take place after some liquids are removed from their container and exposed to air, but decanting by itself is not a change.
