Question
Purpose To identify the limiting reactant experimentally and to determine the percent yield of the product. Procedure 1. Mass approximately 3 g of NaHCO3 and record the exact mass in your data table. Keep off to the side for later. 2. Mass a balloon and record that mass in your data table. 3. Measure approximately 30 mL of a 5% vinegar solution. Record the exact volume in your data table. 4. Add the measured acetic acid to a 125-mL flask. 5. Test the pH of the acid by dipping a glass stir rod into the solution and then touching it to a piece of pH paper. Record the pH in your data table. Save this paper for a later step. 6. Carefully pour the sodium bicarbonate into a balloon using a funnel. Using the technique your teacher showed you, attach the balloon to the mouth of the flask. When you are ready to start the reaction, lift the balloon up so ALL the sodium bicarbonate drops into the flask. Swirl the flask to mix the chemicals until the reaction seems complete. Record observations. Remove the balloon and tie it up so that the gas inside is not lost. Zero a weigh boat on the balance and put your balloon in the weigh boat. Record this mass in your data table. p. 8. Test the pH of the solution in the flask by dipping a glass stir rod into it and touching the pH paper used earlier. Record the pH in your data table. V. Pop balloon with a thumbtack to slowly let the gas out and throw it out. Rinse out your flask with water. Clean up the rest of your lab area. Observations Before reaction took place During the reaction 。 once the baking soda mixed w/ the vinegar the solution bubbled up in uc the flask othe gas from the solution entered the baloon After the reaction
