The Effect of Carbon Dioxide on Salt Water Abstract Background: The human population strongly relies on the oceans for food, transportation, recreation, climate regulation, and half of the Earth's oxygen. These oceans, that we rely so heavily on, are becoming more acidic and less hospitable, making ocean acidification the world's second most important atmospheric carbon problem. This carbon is released into the atmosphere by burning fossil fuels, and hits the ocean, dissolving, and becoming carbonic acid, which is lowering the ocean's pH.
This acidity dissolves the shells that serves as shelters for so many vital species, and because of this, the entire food web is affected. Along with the species, the coral reefs are starting to disappear. To solve this, we must emit less carbon dioxide into the atmosphere, which will lead to the oceans balancing out again. The purpose of this experiment was to find out how carbon dioxide affects salt water. In the experiment we added universal indicator into beakers of 4 types of water(100mL) and then blew carbon dioxide into those different types of water through a straw. The top of the beakers were covered with plastic wrap. We had one person blow into the straw for 2min. Every thirty seconds we recorded what color the water was and matched it up to a pH #. After doing that with all 4 types we were done. The results showed that since more CO2 got into the water as more time went by, the pH lowered. As more time passes by, the pH gets lower and lower each time.
Introduction The purpose of this experiment is to investigate the effect of CO2 exposure on salt water. It is predicted that if salt water is exposed to carbon dioxide over a period of time, then the pH will be lower than what it was in the beginning.
Experimental Procedure Materials:
● A straw
● 500mL beaker
● Universal indicator
● 100mL each of: cold salt water,
