If you had a sample of ocean water, what steps could you take to classify ocean water as a suspension, solution, element or compound?
Evaporate the water. If salt is left behind, the sample is a mixture that can be defined as a solution.
Let the sample settle. If the salt settles to the bottom, it is a mixture that is classified as a solution.
Observe the diffraction of light as it moved through the sample. If light does not scatter, it is a pure substance that is elemental.
