一、有关溶液概念的运用下列物质中不属于溶液的是()A.食盐水B.汽水C.泥水D.澄清石灰水解析通过学习我们知道溶液是由溶质和溶剂两部分组成的,根据教材上的概念我们可以知道,溶液中的溶质可以有多种而溶剂只能有一种。溶质和溶剂之间有一定的选择性,同一溶质在不同溶剂中溶解的情况可能有很大的差异。最重要的是溶质在溶剂的作用下以微观粒子形式存在,不受宏观作用力的影响,因此溶液才具有均一、稳定的特点。此题目中C项泥水中的泥沙由于其粒子受到宏观作用力的影响,因此无法形成均一、稳定的混合物。故C项是错误的。
First, the concept of solution The following substances are not part of the solution is () A. Brine B. Soda C. Slurry D. Clarification of lime water by learning we know that the solution is composed of two parts of solute and solvent, according to the teaching material On the concept we can know that the solute in solution can have a variety of solvents and only one. There is a certain selectivity between the solute and the solvent, the same solute dissolved in different solvents may be very different. The most important thing is that the solute exists in the form of microscopic particles under the influence of the solvent and is not affected by macroscopic force, so the solution has a uniform and stable characteristic. In this project, sediment in C muddy water is unable to form a uniform and stable mixture due to the macroscopic force of its particles. Therefore, item C is wrong.
