In this experiment ethanol, CH3CH2OH, is oxidized by chromic acid, H2CrO4. a) Potassium dichromate, KCr2O7 (aq) reacts with sulfuric acid, H2SO4 (aq) to produce chromic acid H2CrO4 (aq) according to the following reaction. 2 H3O1 (aq) 1 Cr2O7 2– (aq) ? 2 H2CrO4 (aq) 1 H2O (l) The chromic acid H2CrO4 (aq) is made by adding 1.00 mL of 0.0196 M potassium dichromate, KCr2O7 (aq), to 10.0 mL of 3.9 M sulfuric acid, H2SO4 (aq). Calculate the concentration of the chromic acid. b) 10.0 uL of CH3CH2OH is added to 2.00 mL of H2CrO4 (aq). Calculate the concentration of CH3CH2OH in the resulting solution given that the density of ethanol is 0.789 g/mL. c) Ethanol is oxidized by the chromic acid according to the following reaction. 6 H3O1 (aq) 1 3 CH3CH2OH (aq) 1 2 H2CrO4 (aq) ? 3 CH3CHO (aq) 1 2 Cr31 (aq) 1 14 H2O (l) Calculate the concentration of ethanol after reaction goes to completion and the percent change in the concentration of ethanol.
