Why is salt stronger than sugar?

Answer 1

Rather than thinking of sugar dissolving "faster" than salt, look at the situation as a matter of how much

of each dissolves. In other words, a greater weight of sugar will dissolve in a fixed quantity of water

than will salt in that same amount of water. Simpler still, sugar is more soluble than salt. Factors that

influence the amount of each that will dissolve (and the speed at which they dissolve) are the nature of

the solutes themselves, the temperature and purity of the water, and whether the solution is stirred during

the dissolution process.

Salt is an ionic compound -- that is, the sodium and chloride parts are charged particles, Na+ and Cl-. The

bonds that join these ions in the crystal are very strong. That's why salt is so very hard to melt. Sugar

melts easily because the bonds that hold those molecules together in the solid (crystalline state) are much

weaker.

What is true in the solid state is not necessarily evident when these materials are asked to dissolve in

water. Both the ions comprising salt and molecules of sugar can interact with water once these particles

are freed from their crystalline states by the dissolution process. Once dissolved and free to move within

the solution, the bonds between sugar molecules and water are more numerous in number than those that can

form between the Na+ and Cl- ions in salt. So, as sugar molecules dissolve from the crystal, they are

immediately surrounded by water molecules that insulate them from recombining with the crystal. This also

happens when the ions of salt are free of the crystal. Even so, the opportunities for bonding with water

molecules are fewer with salt than with sugar because the ions are very small when compared to the size of

sugar molecules.

The initially stronger ionic bonds in salt and the more numerous water-sugar bonds that form after

dissolution gives sugar the solubility edge. Thus the greater solubility of sugar over salt.

Answer 2

Because salt has a stronger structure and bond than sugar.

Answer 3

Table salt has a melting point of 1474 degrees Fahrenheit.Salt has a higher melting point than sugar because it is created from the ionic bond of two elements sodium and chloride,
