What is the section that is left that is not sediment?

• A. Precipitate
• B. Pellet
• C. Sediment
• D. Supernatant

Answer: (D)

When a mixture is separated by letting solids settle or by spinning them down, the heavier solids move to the bottom while the lighter liquid stays above. The liquid that remains above the settled solids is called the supernatant. That’s the portion left after the solids have settled. So the section that is left and is not sediment is the supernatant. The other terms refer to different portions: a precipitate is a solid formed from a reaction in solution, a pellet is the compact mass of solids at the bottom after centrifugation (part of the sediment), and sediment is the settled solids themselves.
