Creating the Five Environments 18/02/13

Today, the solutions were created (Steps 4-7 of method). The oxygenated water environment consisted of distilled water, where 160mL was added to each of the four cups. The deoxygenated water environment was also made which had 140mL of oxygenated water, with a 20mL Oil layer covering the surface of the water. The warm water solution was created using 110mL of boiling water, mixed with 50mL of room temperature distilled water. The Salt water environment was created using 160mL of distilled water, with one teaspoon of sodium chloride added, and the cold water environment was created by using 100mL chilled water, combined with 60mL of room temperature water. These solutions were added to the cups labelled according to the solution, and left in the lab for signs of corrosion.
