许多物质都必须把它首先制成溶液,然后再加以应用。研究物质溶解性规律,是一个很有实用价值和理论意义的课题。本文拟对物质的溶解性和溶解度问题,作一综合性论述,以供化学教师在教学中参考。 一、常用溶剂分类 溶剂分类方法很多。按是否有机物来分,分无机溶剂与有机溶剂。常用的无机溶剂有水、无机酸、无机碱、有机溶剂有羧酸、醇、醛、酯、醚、卤代烃、烃类、胺类。按溶剂有无极性分,分为极
Many substances must be made into solution first and then applied. Studying the law of substance solubility is a topic of great practical value and theoretical significance. This article intends to substance solubility and solubility issues, for a comprehensive discussion for the chemistry teachers in teaching reference. First, the common solvent classification Many solvent classification. According to whether organic matter points, points inorganic solvents and organic solvents. Common inorganic solvents are water, inorganic acids, inorganic bases, organic solvents are carboxylic acids, alcohols, aldehydes, esters, ethers, halogenated hydrocarbons, hydrocarbons, amines. According to the polarity of solvent points, divided into very
