摘　　要：借助手持技术通过电化学方法测定乙醛与新制氢氧化铜反应的电压变化情况,揭示了该反应的本质,通过控制变量的思想探究了NaOH在该反应中所起的作用,并结合相关文献知识和实验对比进一步探究了乙醛与新制氢氧化铜反应产物的成分。The essence of the reaction was revealed by measuring the voltage change of the reaction between acetaldehyde and the new copper hydroxide by electrochemical method with the help of hand-held technology. The role of NaOH in the reaction was explored by the idea of controlling variables. The composition of the reaction product of acetaldehyde and the new copper hydroxide was further explored by combining the knowledge of relevant literature and experimental comparison.
