Final answer:

Solubility of solids and gases change with temperature, affecting the amount that can dissolve in a solution.


Explanation:

Solubility and Temperature

Saturated vs. unsaturated solutions: In a saturated solution, no more solute can dissolve at a given temperature, while in an unsaturated solution, more solute can dissolve. Effects of temperature: Generally, the solubility of solids increases with temperature, while the solubility of gases decreases.

  1. NaCl: 36g at 0°C, 39g at 100°C
  2. KCl: 34g at 0°C, 56g at 100°C
  3. NH4Cl: 29g at 0°C, 41g at 100°C
  4. Ca(OH)2: 0.189g at 0°C, 0.211g at 100°C
