分析终态法 ,是指在审题分析中 ,不去过分考虑变化中复杂的中间过程 ,而只求最终结果 ,通过对终态物质的分析 ,联系始态 ,找出关系式 ,从而达到迅速解题的目的 .例 1　将若干克氧化铜粉末加入到 5 0ｇ溶质质量分数为 19 6 %的硫酸溶液中 ,微热至氧化铜全部溶解 ,再向该蓝色溶液 The analysis of the final state method means that in the analysis of the trial questions, it is not to over-consider the complicated intermediate process of change, but only to seek the final result. Through the analysis of the final state matter, the initial state is found and the relationship is found, so that a rapid solution can be achieved. Purpose of the Example. Example 1 Several grams of copper oxide powder were added to 50 g of a sulfuric acid solution with a solute mass fraction of 196 %, and the solution was slightly warmed until the copper oxide dissolved completely and then the blue solution was
