isobaric solution a solution having the same specific gravity as a standard of reference.
isotonic solution one having an osmotic pressure the same as that of a standard of reference.
molar solution a solution in which each liter contains 1 mole of the dissolved substance; designated 1 M. The concentration of other solutions may be expressed in relation to that of molar solutions as tenth-molar (0.1 M), etc.
normal solution a solution in which each liter contains 1 equivalent weight of the dissolved substance; designated 1 N.
ophthalmic solution a sterile solution, free from foreign particles, for instillation into the eye.
saturated solution one in which the solvent has taken up all of the dissolved substance that it can hold in solution.
sclerosing solution one containing an irritant substance (sclerosing agent) that will cause obliteration of a space, as in sclerotherapy.
standard solution one that contains in each liter a definitely stated amount of reagent; usually expressed in terms of normality (equivalent weights of solute per liter of solution) or molarity (moles of solute per liter of solution).
supersaturated solution an unstable solution containing more of the solute than it can permanently hold.
volumetric solution one that contains a specific quantity of solvent per stated unit of volume.
