标题Re: [发问] 溶液的沸点与凝固点

The impurities "defect" the crystal lattice of the compound. A pure compound
is a structure of high molecular symmetry. An impurity is rather
assymetrical, or is a poorly organized structure. If the impurites are
present with the pure compound, the melting point will deviate because
melting point is also dependent on the high symmetry and organization of
molecular structure.
简单说 他影响了固体晶格的堆积 造成晶格缺损
使得在比较低的温度就开始融化
所以凝固点下降
