The saturation temperature for 20.7g of CuSO4 soluble in water is:
- Option 1: 100°C - This is the correct answer. Copper sulfate (CuSO4) is known to be highly soluble in water, and at standard conditions, it dissolves in water at temperatures around 100°C. This is a typical saturation temperature for such solutes.
- Option 2: 1000°C - This is much too high and not the correct answer. Copper sulfate does not require such high temperatures to reach saturation.
- Option 3: 200°C - This temperature is still too high for the saturation of CuSO4 in water, making it an incorrect option.
- Option 4: 300°C - This is also not the correct saturation temperature for copper sulfate in water.
Explanation:
The saturation temperature refers to the temperature at which a given amount of solute (in this case, CuSO4) will dissolve completely in a solvent (water). For CuSO4, around 100°C is the typical saturation temperature, where the solute reaches its maximum solubility in water under normal conditions.
