Question
Why must your line intersect the origin of the graph ( zero concentration equals zero absorbance)? Explain
Answers
MathMate
The origin is a known point, because it is not possible to have zero absorbance with non-zero concentration and vice versa.
If the straight line has good correlation but does not pass through the origin, a systematic error would be suspected, such as calibration of instrument, etc.
