1相关概念的区别与辨析1)电解质和非电解质电解质是指在水溶液或熔融状态下能够导电的化合物．强调电解质必须是化合物,单质不是电解质,也不是非电解质;且只要在水溶液和熔融状态2个条件中,任一条件下能够导电的化合物,就是电解质．不过SO2等化合物,虽然溶于水后能够导电,导电的原因是由于生成H2SO3的缘故,所以SO2等化合物不 1 The difference between the relevant concepts and analysis 1) Electrolyte and non-electrolyte electrolyte refers to the conductive compound in aqueous solution or molten state. It is emphasized that the electrolyte must be a compound, that the element is not an electrolyte, nor is it a non-electrolyte; and that a compound that can conduct electricity under any condition is an electrolyte as long as it is in an aqueous solution and a molten state. However, compounds such as SO2, although soluble in water, can conduct electricity. The reason for the conductivity is due to the formation of H2SO3, so SO2 and other compounds are not
