This year, the science fair project and experiment chosen was meant to test the effects of various gases on water, to experiment if different gases would change the pH of liquid solutions. To carry out the investigation, three gases, nitrogen, oxygen, and carbon dioxide, were dissolved into 100 mL of distilled water each. While the gases were being added to the water, there were fast-paced bubbles speeding around because the gas was present in the bubbles. Once the liquid was saturated, it was, then, measured for any changes in pH. If the pH was at 7, the pH was neutral. If the pH was higher than 7, it was alkaline. Finally, if the pH was lower than 7, it was acidic. The independent variable was the type of gas and the dependent variable was
