Question

2. The amount of chlorophyll in a pond sample is directly related to the amount of algae in the water. The more algae present in the pond, the more chlorophyll will be in the sample (i.e., the sample will be greener). The pond sample can be treated and run through a spectrophotometer to determine the exact amount of chlorophyll in the sample. The spectrophotometer reads the absorbance (which is based on color) and compares it to values established with a standard curve.

Is this sort of assessment quantitative, qualitative, or semi-quantitative?

Explanation / Answer

This kind of assessment is called semi-quantitative. As the spectrophotometere gives the exact value of the amount of chlorophyll present in the sample. And it compares with the range of values estalished with a standard curve, By doing this, errors can be ignored and a safe solution can be arrived at.
