So we first took hydrogen peroxide and poured 3mL of it into a graduated cylinder and then poured 3mL of it into the three test tubes we had. After we poured the hydrogen peroxide into the tubes we took three different mixtures into the tubes. Those mixtures were Diet Coke, Skim Milk, and a stomach antacid. We poured 3mL of those three solutions into their test tubes, which were marked acid, neutral, and base. After all the mixtures were poured into their tubes we had to get 50mL of water and pour it into our beaker. We then added half a teaspoon of yeast into the beaker, to make a yeast solution. We then added two drops of the mixture into one of the tubes and measured the gas pressure. We then repeated the process for the other two tubes. We used logger lite to measure the gas pressures. There was a gas tube that was used to measure to pressurized gas. The measurements for the first tube pressures are in the picture below.
The pressure measurements for the second test tube are in the picture below.
The measurements for the third are below.
As you can see by the pictures each measurement is much different. Some are higher and some are lower in their pressure levels. The pictures go in the order of acid, neutral, and base. The base ended with the most and the neutral ended with the least amount.
