(c) What is the effect of temperature on the solubility of solids in liquids ?
a)Solubility of the substance is the maximum amount of solute that can be dissolved in specific amount of solvent.
if the process is exothermic in nature then the solubility of the substance decreases with rise in temperature.
but if the process is endothermic in nature the solubility of substance increases with increase in temperature
b)This means that at
20∘C is 20.7 g" of copper sulphate can be dissolved in 100 grams of water
solubility is the amount of substance that can be completely dissolved in 100 grams of water at a particular temperature
c)For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart thesolute molecules that are held together by intermolecular attractions.
