基于微型仪器与手持技术的电解质溶解的温度变化实验设计

Experiment Design of Electrolyte Dissolve Temperature Change of MCREI and Handled Technical Equipment

结合了微型化学实验仪器与手持技术设备探究了氯化铵、氯化钠、氢氧化钠固体溶解的温度变化过程;实验结果表明,该微型掌上设备可探究到该实验的历程,且数据丰富,图表直观明晰,可触动学生的探究欲望。

Combined with the mini chemical reaction experiment instrument（MCREI） and handheld technical equipment the temperature changes of ammonium chloride,sodium chloride,sodium hydroxide dissolve process were explored.Experimental results showed that the mini hand-held devices can probe into the experimental process,with rich data and fresh,clear and vivid chart,which can stimulate students＇ inquiry desire.
