In general, an increase in temperature increases the solubility of a solute in water because?
Answer Details
An increase in temperature generally increases the solubility of a solute in water because more solute molecules can dissolve at higher temperatures. When the temperature increases, the kinetic energy of both the water molecules and the solute molecules increases, causing them to move faster and collide more frequently. This leads to more solute molecules being pulled apart and surrounded by water molecules, which increases the solubility. Additionally, for some solutes, such as ionic compounds, higher temperatures can cause more of the solid to dissociate into ions, increasing the concentration of solute particles in the solution and thus increasing solubility.
