Temperature 342 Question Answer What happens when you raise the temperature of a solvent? What happens to the solubility of Salt as temperature increases? Why does temperature increase the Solubility of solids? The solute becomes more soluble as Temperature increases. Salt becomes more soluble as temperature goes up. The particles of the solvent move faster Breaking up the solute. What happens to gas as temperature Increases? The solubility decreases as temperature Goes up.

Solubility and Temperature p. 342 u Draw Evidence Based on what you have read and the data in the table, do you think silver nitrate is a solid or a gas? Explain u Silver nitrate is a solid because as temperature rises it becomes more soluble. At 0 C it is 122 but at 50 C it increase to 455
