Use a pH sensor to investigate chemical reactions important in the formation of acid rain to understand the relationship between man-made emissions, acid rain, and problems arising from acid rain.
In this activity, students investigate chemical reactions that are important in the formation of acid rain to better understand the relationship between certain types of man-made (anthropogenic) emissions and problems arising from acid rain. During this investigation, students:
