甲醛与新制氢氧化铜反应的产物及影响因素的探究

Inquiry on Reaction Products and Influencing Factors of Formaldehyde and Newly Produced Copper Hydroxide

结合扫描电子显微镜技术和X射线衍射技术对甲醛与新制氢氧化铜反应的固态产物进行微观层面探究。主要考察反应温度、甲醛和硫酸铜的量对固态产物的成分以及微观形貌的影响。为培养学生的“科学探究”和“宏微结合”核心素养提供新素材和新视角,对一线实验教学的开展具有借鉴意义。

The combination of scanning electron microscope and X-ray diffraction was applied in exploring the solid products of formaldehyde and freshly prepared copper hydroxide at the micro level.It mainly explored the influence of reaction temperature,the amount of formaldehyde and copper sulfate on the components and the crystal morphology.It provided new materials and new perspective for cultivating students’“scientific inquiry”and“combination of macro and micro”core literacy,and had reference significance for the development of first-line experimental teaching.
