The hydrogen sulfide in a 75.0-g sample of crude petroleum was removed by distillation and uncollected in a solution of CdCl2. The precipitated CdS was then filtered, washed, and ignited to CdSO4. Calculate the percentage of H₂S in the sample if 0.115 g of CdSO4 was recovered.
Vitamin C (ascorbic acid, C₆H₈O₆, 176.12 g/mol) can be measured by redox titration with iodine solution. Iodine is reduced to iodide ion, while ascorbic acid is oxidized to dehydroascorbic acid (C₆H₆O₆). The iodine solution is usually made in the presence of iodide ion, forming the more stable triiodide ion, I₃⁻, giving the following overall reaction C₆H₈O₆(aq) + I₃⁻(aq) + H₂O(l) → C₆H₆O₆(aq) + 3I⁻(aq) + 2H⁺(aq) The titration is carried out in the presence of starch, which forms a dark blue complex with the excess iodine when the endpoint is reached. You are testing a new multivitamin pill for its vitamin C content. One pill weighing 0.763 g is dissolved in dilute acid and titrated with 0.0236 M I₃⁻ solution, requiring 28.3 mL to reach the endpoint. Calculate the percent by mass of vitamin C in the pill.

15). If Ca(NO3) (aq) is slowly added to solution containing CO32– and SO42– what compound would precipitate out first given the solubility products (Ksp (CaSO4) = 2.4 x 10–5 and Ksp (CaCO3) = 8.7 x 10–9)? CaCO3 would precipitate first because it is least soluble. CaSO4 would precipitate first because it is least soluble. CaCO3 would precipitate first because it is more soluble. CaSO4 would precipitate first because it is more soluble.
