Usually, the fluid is translucent. The term is best applied to the liquid above a precipitation reaction, after the precipitate has settled out, or to the liquid above the pellet from centrifugation. However, it may be applied to describe liquid after sediment has settled out of any mixture. Source Zumdahl, Steven S. (2005). Chemical Principles (5th ed.). New York: Houghton Mifflin.
