1. In this experiment, you will make a set of solutions containing different concentrations of crystal violet (CV*) by mixing different volumes of a stock CV* solution with water to give final volumes of 3.0 mL. The stock solution of CV+ has a concentration of 2.0 x 10-5 M and is dark purple. The diluted solutions will be prepared in cuvettes. 2.0 x 105 M CV* (purple) H₂O V₁ diluted samples of CV* in cuvettes 3.0 mL= V2 Use c₁V₁= C₂V₂ to calculate the volume of the stock 2.0 x 105 M CV+ AND the volume of water to make a 3.0 mL sample of 7.5 x 10-6 M CV+.

Procedure: Step 1: Pipet 25 mL of prepared sample solution, which has been prepared into a 250 mL Erlenmeyer flask. Step 2: Add 3-5 drops of phenolphthalein indicator solution to the sample solution in the 250 mL Erlenmeyer flask. Step 3: Rinse the buret with three 10 mL portions of standardized 0.1 M HC1 acid solution, before fill this acid solution into the buret and record the initial volume of this acid solution in the burette. Step 4: Titrate the sample solution with the standardized 0.1 M HC1 to the endpoint and record the final volume of this acid in the burette. (Note: phenolphthalein endpoint is from pink color to colorless) Step 5: Repeat the titration for two more times. Step 6: Repeat the same procedure from step 1 to step 5 by using methyl orange as an indicator rather than phenolphathelein. (Note: methyl orange endpoint is from orange to red color). Calculate the alkalinity of the sample for both the indicators and potentiometric method using the following equation: [Alk]…
