Corrosion is a common concern that arise from the use of iron metal components in daily life, both at home and industrial scale. Cathodic protection employing a sacrificial anode is one of several ways for preventing iron corrosion and it is a common industrial method for preventing corrosion in underground pipes, ships, and storage tanks. The metal to be protected and a second metal called a sacrificial anode are the two essential components of this corrosion prevention approach. This study involved preparing corrosive cells with different media for different periods of time. It aimed to application the principle of sacrificial anodes by using zinc and iron as sacrificial anodes for the protection to iron and copper respectively in different pH corrosive media (1,3,5,7,9 and11) with different immersion times (30, 60 and 90 days). The magnitudes of percentage of corrosion (% corrosion) and corrosion rate (CR) was observed by weight loss method for Fe without protection, Fe/Zn couple and Fe/Cu couple. The CR varies with varied immersion times and acid alkaline concentrations, according to the findings. The findings showed a large CR in acidic media, with varying degrees, compared to the alkaline and neutral media. A promising results were obtained in which corrosion rates were reduced and determined by applying protection with the sacrificial anode.
