Impact of Temperature on Salt Solubility

Medium Research Summaries Interpreting Results

In a study examining the relationship between temperature and the solubility of a particular salt, researchers conducted an experiment.

They dissolved increasing amounts of the salt in water at different temperatures (20°C, 40°C, 60°C, and 80°C). The goal was to determine how temperature affects the amount of salt that can be dissolved in water. The researchers recorded the maximum grams of salt that could be dissolved in one liter of water at each temperature.

The results showed that at 20°C, the solubility was 35 grams, at 40°C it was 50 grams, at 60°C it was 65 grams, and at 80°C it reached 85 grams. Based on these results, which conclusion can be made regarding the relationship between temperature and the solubility of the salt?
