Gas Laws By: David Mulkey 1. For this experiment all of the materials were acquired first. Once they were acquired three different pieces of string that were to be used in the experiment were measured in grams on a balance. This was done so that the weight of the string could be subtracted from the weight of the string with bicarbonate tablets tied to them once they were measured. Then a constant pressure gas/volume apparatus was set up so that the pressure inside the apparatus is equal to the pressure outside of the apparatus when the levels of water are at the same height on both sides of the apparatus. After these weights were acquired the strings were hung in an Erlenmeyer flask filled with 50mL of dilute acidic acid by using the special stopper from the apparatus. Once this was done the flask was tilted so that the acidic acid came in contact with the tablets which caused a reaction to occur that produced a gas that pushed the water in the apparatus down allowing measurements to be recorded of how many milliliters of water was pushed down
