(208) Corrosion in an electrochemical cell always starts at the
- cathodic surface.
- surface of the metal.
- weakest point in the metal path.
- point where the electrolyte contacts the anode.
Correct Answer

A. surface of the metal.

Explanation

In an electrochemical cell, corrosion occurs when a metal reacts with its surrounding environment, typically in the presence of an electrolyte. The corrosion process begins at the surface of the metal, where the metal atoms come into contact with the electrolyte. This is because the metal surface is exposed to the corrosive agents in the environment, such as moisture or chemicals, which initiate the corrosion reaction. As a result, the surface of the metal is the starting point for the corrosion process in an electrochemical cell.

- Rapid and severe.
- Slow and superficial.
- Rapid and superficial.
Correct Answer

A. Rapid and severe.

Explanation

When the anode is smaller than the cathode in an electrochemical corrosion cell, the rate of corrosion is rapid and severe. This is because the anode is the metal that undergoes oxidation and corrodes, while the cathode is the metal that undergoes reduction and is protected from corrosion. When the anode is smaller, it has less surface area for oxidation to occur, causing the corrosion to be more concentrated and intense, leading to a rapid and severe rate of corrosion.

- Be fit tested with the same make, model, style, of respirator that will be used in the workplace.
Correct Answer

A. Be fit tested with the same make, model, style, of respirator that will be used in the workplace.

Explanation

Before wearing a respirator with a tight-fitting face-piece, it is necessary to be fit tested with the same make, model, and style of respirator that will be used in the workplace. This ensures that the respirator fits properly and provides an effective seal. Thoroughly cleaning and disinfecting the respirator, inspecting for damaged parts, and ensuring that no facial hair comes between the sealing surface of the face-piece are important steps for maintaining the respirator's functionality, but they are not specifically required before wearing it.
