Temperature And Solubility

Decent Essays

At what temperature is more KCl able to dissolve: 40°C or 90°C?

90 C since with the KCl we found that the higher the temperature the more likely the substance is to have greater solubility.

How is temperature related to the solubility of a salt? Explain your answer.

Solubility increases with temperature because the increase in kinetic energy allows the solvent molecules to break apart the solute molecules that are held together by intermolecular attractions.

Which salt is more soluble, KCl or NH4Cl? Explain your answer.

NH4Cl since the data shows us that it requires less heat than KCl to fully dissolve.

Why is it important to not allow the test solutions to boil?

Because if it boils then some of the solvent will be lost
