Question

What is the purpose of applying acid resisting coatings to vulnerable buildings?

1) To protect the buildings from corrosion caused by acid exposure
2) To enhance the aesthetic appearance of the buildings
3) To increase the structural strength of the buildings
4) To reduce the maintenance cost of the buildings

Answer 1

The correct answer is option 1: The primary purpose of applying acid-resistant coatings to buildings is to protect them from corrosion caused by acid exposure, not to enhance aesthetics, increase structural strength, or reduce maintenance costs.

Step-by-step explanation:

To protect the buildings from corrosion caused by acid exposure. Buildings and structures are often susceptible to damage from environmental factors, one of which is acid rain and the dry deposition of acidic particles.

These can lead to the corrosion of metals such as bronze and the deterioration of certain paints and stone materials like marble and limestone. Applying acid-resistant coatings is a form of prophylactic protection, a preventative measure that adds a barrier to vulnerable materials to prevent or slow down the corrosive process.

This may include coatings of metals that form protective oxide layers, such as chromium, or non-metal layers that shield the underlying material from oxygen and moisture. While enhancing the aesthetic appearance, increasing structural strength, and reducing maintenance costs can be side benefits, they are not the primary purpose of acid-resistant coatings.
