Question

Which statements are true? Check all that apply. Check all that apply. The higher the temperature, the more soluble most ionic solids are in water. As you cool a saturated solution from high temperature to low temperature, solids start to crystallize out of solution if you achieve a supersaturated solution. The higher the temperature, the more soluble most gases are in water. If you raise the temperature of a saturated solution, you can (usually) add more solute and make the solution even more concentrated.

Answer 1

The temperature dependence of solubility can vary depending on the substance. For gases, the solubility increases with higher temperatures, while for ionic solids, it decreases. Cooling a saturated solution can lead to the crystallization of solids.

Step-by-step explanation:

The statements that are true are:

1. The higher the temperature, the more soluble most gases are in water.
2. If you raise the temperature of a saturated solution, you can (usually) add more solute and make the solution even more concentrated.

When it comes to ionic solids, the higher the temperature, the less soluble they are in water. As you cool a saturated solution from high temperature to low temperature, solids start to crystallize out of the solution if you achieve a supersaturated solution.

Answer 2

The higher the temperature, the more soluble most ionic solids are in water

As you cool a saturated solution from high temperature to low temperature, solids start to crystallize out of solution if you achieve a supersaturated solution.

If you raise the temperature of a saturated solution, you can (usually) add more solute and make the solution even more concentrated.

Step-by-step explanation:

For many ionic solids, solubility in water increases with increase in the temperature of the solution.

This implies that increasing the temperature allow more solute to dissolve in the solvent, supersaturation may be achieved by so doing. As the solution is cooled, the solid crystalizes out of solution hence the answers above.
