At room temperature, you need at least 100 grams of water to dissolve around 35 grams of salt; however, if the temperature changes, the amount of salt that water can dissolve also changes. Adding salt as the solute to water (solvent) at water’s freezing temperature disrupts the equilibrium of water. Place beaker over Bunsen burner. A gram of salt can be dissolved in 100 ml of water. One factor to consider when studying salt solubility in water is the kind of salt used. In room temperature, the saturation point is reached when the water is no longer able to take in any salt molecules, thereby forming two separate layers of solute (salt) and solvent (water). The solution is saturated with salt. So if it is completely dissolved at that temperature, that is, it can hold more solute in solution . The point where water can no longer dissolve salt is called saturation, and this happens when the salt you add only goes to the bottom of the solution. • We want to find how much salt can dissolve in 200mL of water at 25°C. Solubility and Factors Affecting Solubility. Add prepared salt and start timer. "Salt dissolved in water" is a rough description of Earth's oceans.
