After filtering a water sample for color analysis, which type of color is being determined?

Apparent color
True color
Specific color
Visible color

The correct answer is: True color

When filtering a water sample for color analysis, the type of color being determined is true color. True color refers specifically to the color of a water sample after it has been treated to remove particulate matter, which can interfere with color measurements. This process involves filtration, allowing for a more accurate assessment of the intrinsic color of the water, which is caused primarily by dissolved substances, such as organic materials and minerals. Determining true color is important in water quality assessments, as it helps identify the presence of substances that may indicate contamination or the presence of certain pollutants. Apparent color would include the effects of both dissolved and suspended particles, thus not providing an accurate representation of the water's intrinsic color. The terms specific and visible color are not standard classifications used in this context and therefore do not accurately describe the type of color analyzed after filtration.
