At high concentrations, these dye molecules tend to form dimers in solution. a. What is the expected relationship between the absorbance at λmax for the monomer and concentration? b. The formation of dimers will produce a shifted absorbance peak. Do you expect this relationship to hold using the overall concentration of the dye in the methanol solutions? Why or why not? Hint: What relationship do we know about which relates the amount of something to its absorbance? What assumptions do...

1. Define λmax and explain why it is desirable to do the experimental procedure at λmax? 2. around what absorbance would you expect the λmax to be with each color solution? (Blue, green, red, yellow) 3. a pipet is used to make the solution dilutions in lab. suppose in making the dilution, additional distilled water is accidentally added. Will the concentration of the solution be higher or lower that disered? explain.
