Rates of Corrosion >
Perform a first-hand investigation to compare and describe the rate of corrosion of materials in different:
- oxygen concentrations
- temperatures
- salt concentrations

- Obtain several identical samples of a certain material, such as iron.
- Place each sample in its own corked test tube, with the test tubes having conditions varying in the following areas:
- Oxygen concentration.
- Temperature.
- Salt concentration.
- Observe the tubes over a week and record observations.
- It should be observed that:
- Increased oxygen concentration leads to increased rate of corrosion.
- Increased temperature leads to increased rate of corrosion.
- An increased salt concentration leads to increased rate of corrosion.
