Identify a false statement about how to protect iron from corrosion.
A. Coat the surface with oil, paint, or plastic.
B. Attach a metal that is more easily reduced. *******
C. Exclude air and water.
D. Attach a metal that is a better reducing agent.
correct. Normally, in seawater, one attacheds zinc cathodes (zinc easily oxidized, a reducing agent)
Thank you very much :)
I don't think the answer is B. If zinc is more easily oxidized which makes it a better reducing agent, then wouldn't the answer be D.
Actually no, DrBob222, you would be wrong. That was my original answer, but I got it wrong. Letter B is the correct answer for this particular question. Thank you anyway! :)
You have to read the question. It asks which is FALSE.
You're right. I did not read the question right. I missed the word FALSE. Thanks. And Bob P is right as usual.
To identify a false statement about how to protect iron from corrosion, we need to evaluate each statement and determine if it is true or false.
A. Coat the surface with oil, paint, or plastic: This statement is true. Applying a protective coating to the surface of iron can help prevent contact with air and moisture, which are necessary for corrosion to occur.
B. Attach a metal that is more easily reduced: This statement is false. Attaching a metal that is more easily reduced (meaning it will corrode before iron) is actually a common method of protection, known as sacrificial protection or galvanic protection. This process involves attaching a more reactive metal, such as zinc or magnesium, to the iron surface. The more reactive metal will corrode instead of the iron, thus protecting it from corrosion.
C. Exclude air and water: This statement is true. Corrosion occurs when iron reacts with oxygen in the presence of moisture. By excluding air (oxygen) and water from the iron surface, corrosion can be minimized or prevented.
D. Attach a metal that is a better reducing agent: This statement is true. Attaching a metal that is a better reducing agent than iron can also provide protection against corrosion. A reducing agent tends to give up electrons more readily, which helps prevent the oxidation of iron. Examples of metals that are better reducing agents than iron include aluminum and zinc.
Therefore, the false statement is B. Attaching a metal that is more easily reduced is a valid method for protecting iron from corrosion.
