METHODOLOGY
Materials
The materials used for the preparation of T. catappa seeds oil include: Hammer, G-clamp, stainless bowl, roasted T. catappa seeds, plain sheet, empty bottle, funnel, filter paper, stainless tube and trays.
The materials used for the corrosion bath set-up include: Extracted oil from T. catappa seeds, cutter, 1 molar aqueous acetic acid and sulphuric acid, 1 galloon seawater, locally produced iron rods and tin cans, electrical cutter, beakers and transparent jars for the set-ups, graduated cylinders, forceps, trays, distilled water , electronic weighing balance, acetone, stainless bowls and sand papers.

Extraction and Filtration of the T. catappa Seed Oil Manual press method was used to extract the oil from the nuts (Practical Action, 2011), where the seeds were put into the stainless tube with a plain sheet at the bottom and were subjected to pressure using a G-clamp. Then, the oil was collected using a sterile container as a catch brain. This kind of process was repeated until all the seed/nuts were used up. After the oil was extracted, it was then filtered in a funnel using a filter paper. Researchers let the oil drip for 24 hours and measured the filtrated volume using a graduated cylinder (Ramos, M.E. et al, 2011).
Preparation of the Iron rod and Tin can specimens Iron specimens measuring 2 inches in length were cut out from a 10-mm diameter rod using an electrical cutter. Tin specimens measuring 1 x 3 inches were cut out from cleaned tin cans using a cutter. The iron rods were polished with sand paper (Ademoh, 2012). In getting its density, an electrical weighing balance was used to get its mass, and a water displacement method was applied for the …show more content…
While a molar solution of acetic acid was prepared by the following computation:
Density of acetic acid = 1.05;
Purity of acetic acid = 99.9%; and
Molarity of acetic acid = (Density x Purity x 1,000) /(Molecular weight x 100)
i.e., M = (1.05x99.9 x 1,000) / (99.9 x 100) = 10.5.
Using the relationship M1V1 = M2V2, where: M1 = 1; V1 = 1,000; M2 = 10.5; and V2 = unknown, then V2 = M1V1 / M2. Thus, V2 = (1 x 1,000) / 10.5 = 95.24 ml. According to the above calculations, 95.24 ml of concentrated acetic acid was dissolved in 1 liter of distilled water to give the needed 1 molar aqueous solution of acetic acid (Ademoh, 2012).
Corrosion Bath Set-Up One hundred milliliters of saline water and a molar aqueous solution of sulphuric and acetic acid were measured into a different beakers/transparent jars and added accordingly to the weighed quantities of T. catappa seed oil corresponding to 0%, 0.5%, 1%, and 2% of weight of the solution in a beaker. Where 0% serves as a controlled variable and 0.5%, 1%, and 2% indicates the independent variable (Nuhu Ali Ademoh, 2012).
