高中化学教材中硫酸亚铁溶解度引用数据的纠正

Correction of Solubility Data of Ferrous Sulfate in Water in High School Chemistry Textbook

硫酸亚铁在水中的溶解度在高中化学教材《实验化学》人教版和苏教版的引用数据悬殊很大.通过实验测定七水硫酸亚铁在水中的溶解度以便证明教材中引用的溶解度数据是否正确.结果表明,2套教材中硫酸亚铁的表达形式和溶解度数据之间都不吻合,需要对教材中硫酸亚铁溶解度引用数据进行纠正.

There were obvious differences on the solubility data of ferrous sulfate in water in experimental chemistry of high school chemistry textbooks between People＇s Education Press and Jiangsu Phoenix Education Publishing. The solubility of seven water ferrous sulfate in water was determined by experiment in order to prove the correctness of the solubility data quoted in the textbooks. The results showed that the solubility data didn＇t tally with the form of expression in two sets of chemistry textbooks. The solubility data of ferrous sulfate should be revised when the chemistry textbooks are reprinted.
