Question

Consider the situation where a sodium chloride solution, containing some dissolved oxygen, is circulated to cool a steel chamber. which of the following methods listed below will not decrease the likelihood of corrosion of the steel chamber? a. cool the sodium chloride solution b. Add chemical inhibitors to the sodium chloride solution to slow corrosion c. lower the amount of dissolved oxygen within the sodium chloride solution d. couple the steel to a more cathodic metal, thereby offering cathodic protection

Answer 1

To decrease the likelihood of corrosion of the steel chamber, it is important to lower the amount of dissolved oxygen within the solution and add chemical inhibitors to the sodium chloride solution. Cooling the solution and coupling the steel to a more cathodic metal can also help decrease the likelihood of corrosion.

Step-by-step explanation:

Corrosion occurs when a metal deteriorates through oxidation. In the given situation, a sodium chloride solution is used to cool a steel chamber.

To decrease the likelihood of corrosion of the steel chamber, it is important to lower the amount of dissolved oxygen within the solution (option C) because oxygen is one of the main factors contributing to corrosion.

Additionally, adding chemical inhibitors to the sodium chloride solution (option B) can also slow down corrosion by interfering with the corrosion process.

On the other hand, cooling the sodium chloride solution (option A) and coupling the steel to a more cathodic metal for cathodic protection (option D) can help decrease the likelihood of corrosion.
