In this lab experience, students use stoichiometry calculations to predict the mass of product in a reaction of sodium bicarbonate with heat. This lab really helps students practice stoichiometry calculations and understand the molar relationship between reactants and products. Here they are given a target value of product they must generate. The success of their reaction depends on the accuracy of their math. This challenge of hitting a specific value of product gives students an appreciation for how industrial chemists work toward a quota of material to be produced every day.
