Why solubility of sugar in water increases with increase in temp. whereas that of common salt remains same almost?

cuz, sugar decomposes on heating!!!

BY INCREASE IN TEMP................ KSP INCREASES .....................THEREFORE SOLUBILITY INCREASES..........................OF SUGAR............(AS SUGAR IS DECOMPOSED) BUT FOR COMMON SALT ............IT DOESNT & THEREFORE SOL DECREASES

That is because the solvation of sugar in water is an endothermic process and hence high temp favours the solubility. But the solvation of common salt is and exothermic process and low temp favour it. But the heat of solvation is very low.

this all depends upon nature of compound if it is endothermic than increase of temperature increases the solubility of compound while if its nature is exothermic than incrase of temperature decreases the solubility of system.formula islog k1/k2=del H/2.303R[T2 -T1/T1*T2]
