Question
The relationship between absorbance of light by a solution and its concentration should be so that when concentration increases, absorbance .
Solution
The relationship between the absorbance of light by a solution and its concentration is directly proportional according to Beer's Law. This means that as the concentration of a solution increases, the absorbance of light by the solution also increases. This relationship can be expressed mathematically as A = εlc, where:
- A is the absorbance,
- ε is the molar absorptivity (a measure of how strongly the substance absorbs light of a particular wavelength),
- l is the path length through which the light passes, and
- c is the concentration of the solution.
So, if you increase the concentration (c), the absorbance (A) will also increase, assuming that the path length and the molar absorptivity remain constant.
