This post offers a case study of magnesium citrate used as a pharmaceutical. How does adding a dry white powder to water form aqueous magnesium citrate? To understand what occurs requires students to name chemical compounds, balance chemical equations, calculate theoretical yields, limiting and excess reagents, and use elemental percentage composition. A student question set is available as a resource.

The two-page instruction sheet that accompanies the Luster Leaf Rapitest^© Soil Test Kit could be a useful curriculum resource for chemistry teachers for generating discussion about the key aspects of the content or for helping students practice close reading skills. This article will briefly describe the contents of the instruction sheet and suggest possible uses in the general chemistry curriculum by posing questions for students to answer or consider.
