Results Day 9 27/02/13

This was the last day of the investigation. The nails appear to have corroded an extreme amount since the investigation first started. The iron nails all corroded a large amount, with the Na Cl nail appearing to corrode the most, and the warm water and oxygenated water following behind. The deoxygenated water and cold water corroded the least, but significantly more than any of the aluminium metal pieces.

The aluminium has still proven to be very resistant to corrosion. However crevice corrosion has begun occurring on the surface of the aluminium metal placed in the warm water. The metal is quite thin, which resulted in the formation of small holes, in the middle of the metal. The sodium chloride aluminium metal had signs of galvanic corrosion occurring on the surfaces. 

Final Metal in Solution

Results Day 8 25/02/13

After coming back from two days of unrecorded data, the nails appear to have corroded an extreme amount in just this time. The sodium chloride solution, along with the warm water solution have corroded the most. Their solution is colored dark orange and dark amber and smaller amounts of rust are attached to the nail itself. Most corrosion is found in the solution. The NaCl nail is colored black, while the warm water nail is dark orange. The other solutions still have a spiral formation around the nail, with smaller amounts of flakey rust, floating within the solution. 

The aluminum has still proven to be extremely resistant to corrosion, as results have not changed extensively. 

Results Day 7 24/02/13

Data was not collected today as access to the labs was restricted due to the weekend.

Results Day 6 23/02/13

Data was not collected today as access to the labs was restricted due to the weekend.

Results Day 5 22/02/13

The iron metals continued rusting at fast speeds. The salt water solution is still appearing to be clearly rusting the greatest. The warm water solution was the second greatest, but the corrosion has slowed right down. The cold and deoxygenated solution nails are still continuing to rust the least. As for the Aluminium, very little rust has formed, and only occurring on the warm water solution. 

Results Day 4 21/02/12

The iron metals continued rusting at fast speeds. The salt water solution appears to be currently rusting the greatest, with the warm water not far behind. The cold and deoxygenated solution nails are rusting the least. As for the Aluminium, very little rust has formed, and only occurring on the warm water solution.
