Final answer:
The solubility of KBr at 60 degrees Celsius is not provided, so we cannot determine the type of solution based on the given information.
Step-by-step explanation:
According to the provided information, 100 grams of KBr was dissolved in 100 grams of water at 60 degrees Celsius. To determine if the solution is supersaturated, saturated, unsaturated, or neutral, we need to compare the amount of solute (KBr) dissolved to its solubility at that temperature. Unfortunately, the information does not provide the solubility curve for KBr at 60 degrees Celsius. Therefore, we cannot determine the type of solution based on the given information.
