Use the scenario to answer the next two questions Making solutions Solutions are mixtures that are very common in our daily lives. A solution is composed of a solute and a solvent. A student conducted an investigation using 50 milliliter of distilled water and 5 grams of table salt. The water for each test was brought to a certain temperature before the salt was added. The data from the investigation are shown in the graph. Which conclusion best describes the data in the graph? Options: Increasing the amount of solvent increases the temperature of a solution, Increasing the temperature of the solute increases the amount of the solution, the amount of solute in a solution determines the time needed for the solute to dissolve in the solvent, A decrease in the temperature of a solvent increases the time needed for a solute to dissolve in a solvent

Back

A decrease in the temperature of a solvent increases the time needed for a solute to dissolve in a solvent
