Abstract

The article presents a classroom activity concerning the differences between the effects of sodium chloride and calcium chloride on superabsorbent polymer gels. It explores the contraction and swelling of the polymer gel which are due to the charges on metal ions of the two chlorides. It is noted that the study is supported by the National Science Council (NSC) of Taiwan.
