Colorimetry Flashcards
1
Q
What does colorimetry use the relationship between?
A
Colour intensity of a solution and the concentration of the coloured species present
2
Q
A colorimeter or spectrophotometer can be used?
A
To measure the absorbance of light of a series of standard solutions, This data is then used to plot a calibration graph
3
Q
How can the concentration of of the solution being tested can be determined?
A
From its absorbance value and by comparison with the calibration curve.
4
Q
The concentration of the coloured species in the solution in the solution being tested must lie?
A
In the straight-line section of the calibration graph to give an accurate value.
