Both small beakers are full of 25ml of distilled water however, one beaker will be air pressured while the other will be breathed into for five minutes. After those five minutes one must add one drop of universal indactor to both beakers.
The beaker on the left came in contact with carbon dioxide and it changed color from white to yellow due to the universal indicator however, this proves that it has become more acidic in pH level. While, the beaker on right was areated and it changed color from white to green which proves that it is still neutral.
The test tubes with the lime water. The left has a straw to breath into and the right side has a air pressure tube that will put oxygen into the lime water.
The test tube that had a air tube putting air didn't change and stayed neutral but were some bubbles. The left test tube with the straw changed color because it had contact with CO2.
