Answer 1

To determine whether a solution of 40 grams of KCl at 50 degrees Celsius is unsaturated, saturated, or supersaturated, you would typically refer to a solubility curve for KCl which shows how much of the substance can dissolve in a given amount of solvent (usually water) at different temperatures.

You didn't provide the specific values from the solubility curve, but here's a general approach to answer the question:

1. **Find the solubility of KCl at 50 degrees Celsius from the curve**: Look at the curve and see how many grams of KCl can dissolve in 100 grams of water at that temperature.

2. **Compare the given amount (40 grams) to the solubility**:
- If 40 grams is less than the solubility at that temperature, the solution is **unsaturated**.
- If 40 grams equals the solubility, the solution is **saturated**.
- If 40 grams is greater than the solubility, the solution is **supersaturated**.

Without access to the solubility curve image, I can’t provide the specific answer. However, you should be able to follow these steps to find the answer when you have the curve in front of you.
