Abstract The accuracy of yield calculation in the“purification of crude salt”experiment was evaluated.The yield calculation method was improved to avoid higher yield in the traditional calculation by removing extra Na+ and Cl- introduced from reagents.The scientific nature of quantitative calculation should be emphasized during experimental research,thus students’ capability of experimental exploration and scientific consciousness could be cultivated.
