In a chemical context, what does saturate most closely mean?

• A. Make something completely wet with water or other liquid so that no more can be absorbed
• B. Cause a substance to combine with, dissolve, or hold the greatest possible amount of another substance
• C. To dry something thoroughly
• D. To reduce a solution by evaporation

Answer: (B)

Saturation in chemistry means the solvent has dissolved as much solute as it can at the given temperature and conditions. At this point the solution has reached its maximum capacity to hold solute; any extra solute will not dissolve and may stay undissolved or form a precipitate.

This aligns best with describing a state where the substance has combined with, dissolved, or held the greatest possible amount of another substance. The other options describe processes like wetting/absorption, drying, or evaporation, which are different concepts and do not define saturation.
