Hypothesize what your observations will be for the reactions of hydrogen carbonate withthe acids in Part D. Include your rationale. Part D: Part D: Reactions with NaHCO3 and Na2C2O413. Place a small quantity (about the size of an almond or a bean) of sodium hydrogen carbonate (i.e., sodiumbicarbonate) into an evaporating dish. Place the same amount of sodium oxalate into a separate dish.14. Add one dropper’s worth* of 1.0 M H2SO4 to one of the dishes. Note any visible changes (bubbling, smokeformation, color changes, etc.) that occur to the dish’s contents. When the reaction has finished, add adropper of 1.0 M H2SO4 to the other dish and again observe.15. *The dropper does not have to be full, just what one fully squeezed bulb picks up16. Clean the dishes out and set them up as you did before with solid NaHCO3 and Na2C2O4. Add acid to thesalts as you did before, but use 1.0 M HCl instead of H2SO4.
