Last week in science class, students did a lab that let them determine the stoichiometric ratio of reactants that made a gas. In this case the gas was carbon dioxide.
Ms. Medley said this lab let them utilize the skills they learned over the previous two units. She also said the class got to use everyday items to have fun in an educational and safe environment: baking soda, vinegar, and balloons. Ms. Medley shared, “This lab allowed students, through experimentation, to determine the stoichiometric ratio of reactants that generated a gas. In this case, the gas that was produced was carbon dioxide. They used everyday items to have fun but they were actually doing real science.”
By the end of the experiment, they were able to find the number of moles of baking soda (NaHCO3) used in each reaction, and decide which chemical was the limiting reagent in each test tube reaction, and therefore how many moles of carbon dioxide were produced per test tube.
