根据学生学过的相似三角形对应边成比例和同一物质在一定温度下不同质量的饱和溶液里:溶质、溶剂、溶液对应成比例,二者具有很大的类似性,借用相似三角形对应边成比例来解溶解度计算题,给教和学带来了很大的方便。用三角形的三个边分别表示一种饱和溶液的三个量:溶质、溶剂和溶液的质量(三个边只定性表示三个量,因而:溶质的质量+溶剂的质量=溶液的质量),三角形内表示
According to the similar triangles studied by the students, the corresponding sides are proportional and the same substance is in a saturated solution of different masses at a certain temperature: the solute, the solvent, and the solution are proportional to each other, and the two have great similarities, and are proportional to the corresponding sides of similar triangles. Solve the solubility calculation problem and bring great convenience to teaching and learning. The three sides of the triangle represent the three quantities of a saturated solution: the mass of the solute, the solvent, and the solution (the three sides only qualitatively represent the three quantities; thus: the mass of the solute + the mass of the solvent = the mass of the solution), Intrinsic representation
