ARemoving solute from a solution by evaporating the solvent
BLowering a solution's concentration by adding more solvent
CRaising a solution's concentration by adding more solute
DMixing two solutions of the same solute and same volume
Answer & Solution
Correct answer: B. Lowering a solution's concentration by adding more solvent
1. Dilution is the process by which a solution's concentration is lessened.
2. It happens by adding solvent, which increases the total volume of the solution.
3. A glass of iced tea grows more dilute as the ice melts and adds water.
4. Adding more solute would raise the concentration, which is the opposite of dilution.
