To determine whether the 10 grams of KCl (potassium chloride) in solution at 10 degrees Celsius is unsaturated, saturated, or supersaturated, we must compare the amount of KCl present in the solution to the solubility of KCl at that temperature.
- Unsaturated: If the solution can still dissolve more solute at the given temperature.
- Saturated: If the solution has dissolved the maximum amount of solute possible at that temperature.
- Supersaturated: If the solution contains more solute than can normally be dissolved at that temperature, typically achieved through specific cooling or evaporation methods.
In general, solubility data indicates that the solubility of KCl in water at 10 degrees Celsius is around 28.6 grams per 100 mL of water.
Since 10 grams of KCl is significantly less than the solubility limit, we can conclude that the solution is unsaturated.
