.) A student has a sample of ocean water that they take to science class. What steps could be taken to determine to classify the ocean water as
a suspension, solution, element, or compound?
A)
Examine the pH of the sample. If the pH is exactly
neutral, it is a pure substance that is a compound.
B)
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
D) the sample. If light does not scatter, it is a pure
substance that is elemental.
