Solubility

Effect Of Chemical Bonding On Solubility

Not all substances are equally soluble at the same temperature. At 41°F (5°C), the solubility of table sugar is more than three times greater than that of table salt, as shown in Figure 1.

Even substances such as ordinary glass, which appear not to dissolve, actually do so, but their solubility values are extremely small.

The types of bonds or forces that hold sugar particles together are different from those found in glass. The interaction between the attractive forces holding these particles together and the attractive forces to the molecules of solvents accounts for the different solubilities.
