Cоmbinаtiоn оf Isotonics is а PNF technique utilized for __?
A student is studying the cоmpоsitiоn of bronze, аn аlloy mаde from copper and tin. She places a piece of brass into excess hydrochloric acid and hydrogen peroxide, and the copper reacts to make copper (II) chloride. To determine the concentration of the copper (II) ions in solution, he uses colorimetric (spectrophotometric) analysis. The student first determines the appropriate wavelength to use to analyze the copper (II) ion. Then he analyzes a series of solutions of copper (II) of known concentration with a spectrophotometer that has a 1.25 cm cuvette to generate the following data. Trial Concentration (M) Absorbance 1 0.15 0.36 2 0.25 0.60 3 0.35 1.84 4 0.45 1.08 unknown Unknown from bronze sample 0.90 She determines the appropriate wavelength to analyze copper(II) chloride is 810 mn. What is the frequency of this wave? Use the data in the table to calculate the molar absorptivity constant for the copper(II) ions. What is the concentration of copper(II) ions in the unknown solution? If the solution of copper (II) ions analyzed had a volume of 250.0 mL, how many grams of copper reacted with the hydrochloric acid and hydrogen peroxide?
