PREGUNTA RESPUESTA The solubility of solids is affected by temperature while the solubility of gases is affected by both temperature and pressure. The Solubility of Solids The solubility of a solid solute increases with increasing temperature because the thermal energy helps to overcome the attractions between solute molecules in the solid. The Solubility of Gases The solubility of a gaseous solute decreases with increasing temperature because the thermal energy helps to overcome the attractions between solute and solvent molecules. The solubility of a gaseous solute increases as pressure of the solute gas above the solution is increased because a higher pressure means that more gas molecules are present near the surface of the solution and able to dissolve. The ability for a substance to dissolve is affected by both temperature and pressure. Out of the following solutes, which would be the most soluble at 40 °C in 100 g of water?

RESPUESTA
The solubility of solids is affected by temperature while the solubility of gases is
affected by both temperature and pressure.
The Solubility of Solids
The solubility of a solid solute increases with increasing temperature because the
thermal energy helps to overcome the attractions between solute molecules in the
solid.
The Solubility of Gases
The solubility of a gaseous solute decreases with increasing temperature because the
thermal energy helps to overcome the attractions between solute and solvent
molecules. The solubility of a gaseous solute increases as pressure of the solute gas
above the solution is increased because a higher pressure means that more gas
molecules are present near the surface of the solution and able to dissolve.
The ability for a substance to dissolve is affected by both temperature and pressure.
Out of the following solutes, which would be the most soluble at 40 °C in 100 g of
water?
