Introduction to Research
We have been hired by the Wikians of Wiki Wiki to find a way to purify their salt water, so they are not prone to diseases and sickness caused by the consumption of salt water according to the United States Environmental Protection Agency (http://water.epa.gov/scitech/drinkingwater/dws/ccl/sodium.cfm). Bryahna Turro, Emily Hoffman, and Angela Labella will be conducting an experiment on May 10th, 2013 using the many forms of matter and condensation to remove the salt from the contaminated water. This will distill the water, leaving it free of any salt says Ann Marie, with a ph.D in science (http://chemistry.about.com/b/2010/01/01/how-do-you-remove-salt-from-water.htm). This will occur in Emily Hoffman's kitchen. We will do this by allowing the salt to be removed from the water through evaporation, then the pure condensation will collect in the center of our pot, dripping down into the center cup, leaving us with pure water, with a pH of 7. We will use uniodized salt for this experiment. Then, we will repeat the same process using iodized table salt, to determine which will filter faster (extra credit). We will measure the amount of pure water collected every minute (in ml). We will test the pH once again to make sure it has the same that we began with. Drinking too much salt water that is impure can cause hallucination, sickness, dehydration, and brain damage. It contains many living micro organisms and parasites that cause ailments, according to the Wilderness Awareness Agency (http://www.natureskills.com/survival/water-purification-process/). To make sure that these things do not occur, we will then boil the water once again, removing any left over bacteria.This will happen by killing the disease causing organisms, says Chris Tracey (http://www.articlesbase.com/education-articles/how-can-you-get-rid-of-bacteria-that-contaminates-water-1278007.html). We will be using tap water for this experiment, which has a pH of exactly 7. When we add un-iodized sea salt, the pH will become 8. When we add iodized sea salt, it will be 7. When our experiment is completed, the pH should return back to a neutral level of 7. We will test the pH levels before and after purification to be sure that we have properly transformed the water from contaminated to pure. The pH should go from 7 or 8 (salt water) to a neutral level of 7 (pure water). This experiment will be better for the health of the Wikians, and improve our knowledge of chemistry. Our independent variable is the salt, and our dependent variable is the water.
