The solubility of potassium chloride KCl in water is affected by temperature. As the temperature of the water increases, the solubility of KCl generally increases as well. This means that more KCl can dissolve in water at higher temperatures compared to lower temperatures.The relationship between temperature and solubility can be represented by a solubility curve, which is a graph showing the solubility of a solute in this case, KCl in a solvent water at various temperatures. The curve demonstrates that as the temperature rises, the solubility of KCl increases.For example, at 0C, the solubility of KCl in water is approximately 28 grams per 100 grams of water. At 20C, the solubility increases to around 34 grams per 100 grams of water. At 100C, the solubility further increases to approximately 56 grams per 100 grams of water.It is important to note that the effect of temperature on solubility is not always the same for all solutes. Some solutes may have a decreased solubility with increasing temperature, while others may not be significantly affected by temperature changes.In summary, the solubility of potassium chloride in water generally increases with increasing temperature. This means that at higher temperatures, more KCl can dissolve in water compared to lower temperatures.
