This is the last experiment day, Clorox started corroding the aluminum, and Drano provided outstanding results

The Steel Weights & pH 3/11/11:
A: 22.9g pH 9
B: 25.4g pH 10
C: 25.3g pH 10.3
D: 25.4g pH 8
E: 25.8g pH 6.5
F: 25.3g pH 5
There is much change, every place for the steel is corroded slightly, rust orange water for clorox, clear for drano, light blue for ammonia, white powdery for water, dark gray and white on the edges for salt, and whiter for Sulfuric Acid.

The Copper Weights & pH 3/8/11:
A: 18.6g pH 8
B: 18.3g pH 11
C: 18.7g pH 11
D: 19.1g pH 8
E: 17.6g pH 7.5
F: 17.3g pH 4.5
There seems to be lessening corrosion. However, many copper pieces had continuous corrosion, and a some of corrosion today. Clorox has the most, and sulfuric acid has some as well. It is also interesting to see ammonia corroding the metal as well. I finally took my camera to school to take pictures of the metals, but the memory card was full after just the copper. I researched water pollutants, and there is $400 million each year to treat water for just the pesticide Atrazine.

C: 4.2g pH 11
D: 4.5g pH 6
E: 4.4g pH 6
F: 4.3g pH 4The aluminum is being corroded in every category except SA and water. There is a definite gray layer above salt water, and there is slight white powder around clorox and ammonia to show they corroded as well. However, there is no change as much as drano. It went down another 0.1 by today.

There is much corrosion, especially surface corrosion. It does not seem like much, but then I remembered that the green oxidation form comes much later, after the dark form, and most metals are getting darker, except water. This is reinforced by the fact that copper is a extremely good metal for corrosive resistant products, in pipes, it cost 3-4 times as much than steel pipes. The corroded water for clorox is dark dark green, almost none for drano, dark blue for ammonia, none for water, light green for salt water, and none for sulfuric acid

Drano is steadily decreasing, 0.1g per day. I predict that the aluminum oxide will stop corrosion, and there will be less corrosion as I leave it there longer. Some corrosion with salt water, not much.
