Stoichiometry Challenge

This lesson introduces the concept of green chemistry by replacing a conventional aluminum to alum stoichiometry lab with a more sustainable precipitation reaction using sodium carbonate and calcium chloride. Green chemistry is an approach that aims to design chemical processes and products that minimize the use and generation of hazardous substances, while also reducing waste and improving efficiency. By using a greener alternative to the traditional lab, this lesson showcases the principles of stoichiometry, which involve calculating the theoretical yield based on the known concentrations and quantities of the starting materials in a balanced chemical equation.
