The nitrite ion is involved in the biochemical nitrogen cycle. You can determine the nitrite ion content of a sample using spectrophotometry by first using several reactions to form a colored compound from the ion. The following data were collected.
Nitrite Ion concentration (M) Absorbance of solution at 550 nm
2.00 x10^-6 M 0.065
6.00 x10^-6 M 0.205
10.00 x10^-6 0.338
14.00 x10^-6 0.474
18.00 x10^-6 0.598
Unknown 0.402
