Questions Use what you learned in this lab to answer the following questions: A. Suppose a household product label says it contains sodium hydrogen carbonate (sodium bicarbonate). How would you test this material for the presence of sodium bicarbonate? I would test it with several chemicals to see if I would get the reaction like I did in this experiment. The chemical that would prove the presence of sodium bicarbonate is adding HCl and if bubbles are formed, we have proved the
