- Identify the solute and solvent in a solution.
- Classify a solution as unsaturated, saturated, or supersaturated.
- Explain how temperature, stirring, and particle size affect dissolving speed.
What the lesson concludes
- The solvent is present in the larger amount and does the dissolving; the solute is what dissolves into it.
- Solubility is the maximum solute a solvent can hold at a given temperature.
- Unsaturated, saturated, and supersaturated describe how close a solution is to that maximum.
- Diluting adds solvent and lowers concentration without removing solute.
- Heat and stirring speed dissolving for solids; smaller particle size does too.
