Why does salt dissolves in water faster than sugar ?

When we try to dissolve sugar in water , it needs constant stirring . But if we put salt into water , it just disappears in a fraction of second !









WHY ?????

The chemical formula of salt is Na+Cl- . Chemical formula of water is H+2 O - . When we put salt into water , water molecules come between the ionic bonding of salt . Na gets attracted towards O atom of water and Cl towards H atom .

Thus solvation of salt in water occurs . Whereas in sugar , the molecules are quite big and compound . So , breaking of these bonds requires more energy .


This compound bond makes sugar to dissolve less in water . To make the process quick , constant stirring is required .

Salt because of its simple bond structure , dissolves faster in water .
