1. Suppose you need to do an absorption spectroscopy experiment using an orange colored solution. Approximately what wavelength(s) of light would be the worst to measure the absorbance at; what would be the best wavelength(s) of light to measure the absorbance at. Why? Explain your answers in one or two sentences. - Worst wavelength(s): - Best wavelength(s): - Explain: 2. A volumetric flask will be used to make your stock solution and dilutions in this lab. Suppose you fill the flask with the desired substance and then accidentally add distilled water to just above the mark. a) Will the concentration be higher or lower than desired? b) Will you be able to read the new volume? What will you do with this solution? 3. Suppose the molarity of copper(II) sulfate in your stock solution is \( 1.90 \times 10^{-4} \mathrm{M} \) and you take \( 5.00 \mathrm{~mL} \) of this solution, place it into a \( 100-\mathrm{mL} \) volumetric flask and fill it to the mark with distilled water. What is the concentration of the diluted solution (dilution)? Show your work below.
