Basic Wastewater Operator Practice Exam

What is the purpose of amber storage bottles?

1. The color is pretty

2. They are cheaper

3. To protect chemicals that are sensitive to light

4. So you cannot see what is inside the container

The correct answer is: To protect chemicals that are sensitive to light

Amber storage bottles are specifically designed to protect chemicals that are sensitive to light. Many substances, especially certain chemicals and reagents used in wastewater treatment and analysis, can degrade or change their composition when exposed to light. The amber color acts as a barrier, limiting the amount of light that penetrates the container and thereby preserving the integrity of the stored materials. While the aesthetic appeal of the color might be noted, it is not the primary reason for their use. The cost of amber bottles compared to other materials is not significant enough to be a main factor in their selection. Additionally, the opacity of the bottles does not serve the purpose of obscuring visibility, but rather of ensuring that light-sensitive compounds remain stable over time. Thus, the correct focus is on the protective function that amber storage bottles provide against light exposure, ensuring the longevity and effectiveness of the chemicals contained within.
