Answer 1

It seems you're discussing the concepts of solutions and solubility, particularly in the context of saturated solutions at varying temperatures. Let's clarify these concepts and prepare a general understanding based on what you provided:

1. Solution: A homogeneous mixture formed by the dissolution of a solute in a solvent. For example, salt (solute) dissolved in water (solvent).

2. Solute: The substance that is dissolved in a solution. This is typically present in a smaller amount compared to the solvent.

3. Solvent: The substance in which the solute is dissolved. It usually makes up a larger portion of the solution.

4. Types of Solutions:

   • Unsaturated Solution: A solution that can still dissolve more solute at a given temperature. There is not enough solute present to reach saturation.
   • Saturated Solution: A solution that has reached the maximum amount of solute that can be dissolved at a specific temperature. At this point, any additional solute will not dissolve and will remain in the solid state.
   • Supersaturated Solution: A solution that contains more solute than can typically be dissolved at a specific temperature. This state is often achieved through changes in temperature (e.g., heating the solution and then cooling it down without allowing the solute to crystallize out).

5. Solubility Curves: These graphs plot the amount of solute that can be dissolved in a solvent at different temperatures. Each curve represents a different solute. The key points to note from solubility curves include:

   • The curve's upward trend indicates that the solubility of the solute generally increases with temperature (for most solids).
   • The intersection of the curve with the vertical axis indicates how much solute can be dissolved at a specific temperature.

Figures 1 and 2, which you mentioned, likely depict these solubility curves for different salts, showing how their solubility changes with temperature.
