Concernabout corrosion utilized forsale and advertisement of commercial products Concept Introduction: Corrosion is a natural process, which converts a refined metal to a more chemically-stable form, such as its oxide, hydroxide, or sulphide. This may result in the compromise of the structural integrity and stability of the material or structure it is made up of. To avoid this, several methods can be used including covering the surface, adding other metals etc.

Question

Uniform surface corrosion is often expressed as milligram weight loss per square decimeter per day (mdd). A heated mild steel tank containing water is corroding at a rate of 90 mdd. Assume that the mild steel tank corrodes in the same way as iron. The density of iron is 7.87 g/cm³. The depth of corrosion per day is calculated by dividing the corrosion rate in g/(cm². day) by the density of iron. Calculate the depth of corrosion per day for the mild steel tank. Depth of corrosion per day = (__) × 10-4 cm/day (*Show up to 3rd decimal place.) A If the corrosion is uniform, how long will it take to corrode the wall of the tank by 0.3 mm? The number of days required to corrode the steel tank is calculated by dividing the depth of corrosion by the depth of corrosion per day. Number of days = (_) days (*Calculate up to the 1st decimal place.) A

A tin (Sn) component, cadmium (Cd) component, a pure aluminum (Al) component, and a copper (Cu) component are coupled together in seawater. Rank the four in terms of which one will suffer from the greatest corrosion. What type of corrosion is this? Which material (different from the first four) could you use as a sacrificial layer to protect the one that suffers from the greatest corrosion?

For each set of electrodes, fill in the table below. Write the balanced reaction that occurs. You will have each balanced reaction listed more than once. If the anodes are connected correctly to measure the spontaneous reaction, write “Y, otherwise write “N” in the “Spontaneous” column.
