A second general feature of bonding also became apparent in the early days of chemistry. It was found that there are two large classes of compound that can be distinguished by their behaviour when dissolved in water. One class consists of electrolytes: these compounds are so called because they dissolve to give solutions that conduct electricity. Members of the other class, nonelectrolytes, dissolve to yield solutions that do not conduct electricity. The difference between the two classes gave rise to the view that there are two types of chemical bond. Electrolytes produce ions in solution; an ion is an electrically ...(100 of 27318 words)
