Reference no: EM132410005

1. A 15.0 mL wine sample is analyzed for free SO2 (molar mass 64.066 g/mol) using the Aeration-Oxidation method. 2.8 mL of 0.0098 M NaOH is used to titrate the purple solution of captured sulfuric acid to the green endpoint.

a. What is the concentration of SO2 (mg/L) in this wine sample?

b. If the Ripper method were used instead to analyze 50.0 mL of the same wine, what volume of 0.01 M iodine (I2)would be required to reach the blue endpoint?
