How are mixtures and solutions different?

1.Unlike a solution, a mixture has density and will always sink in a liquid because mixtures lack buoyancy.

2.Unlike a solution, a mixture can dissolve completely in a liquid because the properties of the ingredients change.

3.Unlike a solution, a mixture is unable to change states of matter from a solid to a liquid or gas.

4.Unlike a solution, a mixture can easily be separated and each ingredient keeps its physical properties.
