Why are steel bathroom taps often coated with a layer of chromium metal? - Leaving Cert Chemistry - Question B - 2021

Steel bathroom taps are coated with a layer of chromium for several important reasons:

1. Corrosion Resistance: Chromium provides a protective layer that prevents rust and corrosion, which is particularly important in wet environments like bathrooms. This enhances the durability and longevity of the taps.

2. Aesthetic Appeal: Chromium gives a shiny, attractive finish that enhances the appearance of bathroom fixtures, making them more appealing to consumers.

3. Ease of Cleaning: The smooth surface of chromium is easy to clean and maintain, preventing the buildup of grime and scale.

4. Hardness and Strength: The chromium layer adds to the hardness of the surface, making it more resistant to scratches and wear, which is crucial for maintaining functionality over time.

5. Maintenance of Hygiene: Chromium's non-porous surface helps in preventing bacterial growth, contributing to better hygiene in bathroom settings.

In summary, coating steel taps with chromium not only improves their performance but also enhances their visual qualities.
