Question

In terms of saturation (unsaturated, saturated, super-saturated). How would you classify the following?

1. A NaCl solution with a concentration of 50g/100mL of water at 40°C
2. A sugar solution with a concentration of 200g/100mL of water at 40°C
3. A sugar solution with a concentration of 240g/100mL of water at 40°C

Answer 1

1. A NaCl solution with a concentration of 50g/100mL of water at 40°C: The NaCl solution with a given concentration is saturated at this temperature .As the temperature increases the solution will more dissolves.

2. A sugar solution with a concentration of 200g/100mL of water at 40°C: The sugar solution with a given concentration is saturated at this temperature. As the temperature increases the solution will more dissolves.

3. A sugar solution with a concentration of 240g/100mL of water at 40°C: The sugar solution with a given concentration is saturated at given temperature.
