通过重现波义耳发现酸碱指示剂的历史情景和实验探究使学生认识溶液的酸碱性,会用酸碱指示剂判断溶液的酸碱性。在探究活动中培养学生的团结协作精神和严谨的学习态度,体验化学测定在生产、生活中的重要性,认识到应该正确使用化学知识造福人类。
By reproducing the historical scenario of Boyle’s discovery of acid-base indicators and experimental exploration to enable students to recognize the pH of the solution, acid-base indicators will be used to determine the pH of the solution. In the activity of inquiry, we should cultivate students’ unity and cooperation attitude and rigorous study attitude, and experience the importance of chemical determination in production and life. We should realize that we should use chemical knowledge correctly to benefit mankind.
