Recently the urban stream in your neighborhood started turning orange, with slimy colored deposits on rocks and in the steam bed. You suspect that this is due to the presence of iron-oxidizing bacteria. After obtaining a water sample, you decided to test the water to figure out what the orange colored deposits are. Explain how you will experimentally determine the identity of the orange substance given the instruments and chemicals available in a chemistry lab.
Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.
