What is the best prediction for solubility at 150 degrees Celsius for KBr in water?

• A. 100 g KBr per 100 g H2O
• B. 120 g KBr per 100 g H2O
• C. 130 g KBr per 100 g H2O
• D. 150 g KBr per 100 g H2O

Answer: (C)

The solubility of potassium bromide (KBr) in water increases with temperature, which is a common characteristic of many solid solutes. At 150 degrees Celsius, the solubility of KBr is quite high due to this temperature increase, which favors the dissolution process. Typically, KBr shows a significant increase in solubility compared to its solubility at lower temperatures. Empirical data from solubility charts for KBr indicate that the solubility at elevated temperatures can reach around 130 grams per 100 grams of water. This makes the prediction of 130 g KBr per 100 g H2O reasonable and substantiated by scientific literature. Other figures for solubility at this temperature, such as 100 g or 120 g per 100 g of water, do not accurately reflect the strong increased solubility expected at 150 degrees Celsius. Similarly, a prediction of 150 g per 100 g of water likely exceeds the known solubility limit for KBr in water at that temperature. Thus, the choice of 130 g KBr per 100 g H2O stands as the best and most scientifically supported prediction for solubility at 150 degrees Celsius for KBr
