Purpose The purpose of this experiment is to demonstrate the concept of gas laws, which includes gas volumes and pressures. This is demonstrated by creating an “airbag”. It is created by a chemical reaction that will produce gas and inflate the bag. Procedure The first part of the experiment consists of determining the volume of the bag by measuring the amount of water that fits into it. The second part of the experiment consists of mixing the measured amount of sodium bicarbonate and acetic acid in the bag and observing it inflate. Data Bag Dimensions 17.8cm x 19.5cm Bag Volume (L) 1.31L Moles of CO2 Needed 5.4*10^-2 mol Moles of NaHCO3 Needed 5.4*10^-2 mol Moles of CH3COOH Needed 5.4*10^-2 mol Grams of NaHCO3 Needed 4.54g Volume of 6.0 M CH3COOH Needed 9mL Observations When the sodium bicarbonate and the acetic acid were combined, they began fizzing and bubbling. The bag slowly expanded until the bag was fully inflated. Success or Failure
