Question 10 Ethyl Mercaptan (C₂H5SH) is a colorless or yellowish liquid or a gas with a pungent, garlic or skunk-like odor. The concentration of this compound was determined by shaking a 3.88 g sample with 53.39 mL of 0.01204 M lodine (12) in a tightly stoppered flask. The reaction is shown below. 2 C₂H5SH + 12 → C₂H5SSC2H5 +21+ 2H+ The excess 12 was back titrated with 18.94 mL of 0.01437 M Na2S2O3 according to the reaction: Calculate the percentage C₂H5SH (MW = 62.14 g/mol). Express the answer up to three (3) decimal places. 12(aq) + 2 S2032 (aq) → 21" (aq) + $406²-(aq)
