Abstract

The purpose of the research and experimentation presented was to determine if Nasturtium officinale can inhibit the corrosion of unoxidized steel. It was hypothesized that if all the components of a watercress plant are placed with 1M sulphuric acid then the metal placed with the plant will be protected from corrosion more than without the plant present. Distilled water and all parts of the watercress were placed in a glass test tube. The steel metal samples were weighed and added to the water and plant solution. After 24 hours, the samples were taken out of the solution to be weighed and observed under a stereoscope. The control group used the same method but did not add the watercress. The data were collected and statistically analyzed. The data showed that the control group that had no watercress had a larger difference between the mass taken before and the mass taken after than the experimental group with watercress. This suggests that the addition of watercress did inhibit the corrosion of the steel samples. A two sample t-test was performed to tell if the results were statistically significant. The test formula was t(37) = 43.60 when p < 0.05. From this, it can be determined that the results are that the watercress helped inhibit corrosion of steel is significant. Watercress can be planted and possibly protect metal pipes in an environment where acid rain is a frequent phenomenon.
