the part of a solution present in the largest amount solvent
the substance that is present in a solution in a smaller amount and is dissolved by the solvent solute
a mixture containing small, undissolved particles that do not settle out colloid
a mixture in which particles can be seen and easily separated by settling or filtration suspension
a mixture that has only a little solute dissolved in a certain amount of solvent (sap) dilute solution
