Effect of Ph Level on Corrosion Rate
THE EFFECT OF pH LEVEL ON CORROSION RATE A Long Laboratory Report Presented To; The Department of Chemical Engineering BY IGBOKWE C.E (Group C) 090401024 In Partial Fulfillment Of the Requirements for the course Chemical Engineering Laboratory II CHG 310 University of Lagos Date submitted; 12/07/2012
ABSTRACT This experiment involves determining the effect of pH on the corrosion of metals. Corrosion is dependent on a host of factors like temperature, nature of material, humidity, pH etc, but this experiment focuses on pH as a factor. The experiment is thus carried out on three samples each of aluminium, copper and stainless steel. The samples were weighed, then subjected to immersion in different solutions. The three solutions used were conc. sulphuric acid, water and conc. Naoh solution. These solutions were chosen so that the range of the pH scale is covered as much as possible, with each having pH values of 4, 7, and11 respectively. After a certain time of immersion, the metal samples were removed, washed, dried and reweighed. The weight losses were used to calculate the rates of
