21. (WCSU[x]) The оceаn is sаid tо cоntаin one hundred trillion million dollars of gold (Au) in the form of gold(III) chloride. For decades, chemists (and wannabes) have attempted to precipitate gold from seawater, albeit unsuccessfully. One method would be to form an insoluble gold salt. Then, by a redox reaction, reduce the gold ions to pure gold ($$$!). a. (6 points) In theory, sodium hydroxide could be used to precipitate gold from seawater. Write the net ionic equation for the reaction below. Start with the complete ionic equation and identify spectators. AuCl3(aq) + 3 NaOH (aq) ⟶ Au(OH)3 (s) + 3 NaCl (aq) b. (4 points) Provide an alternative anion to hydroxide that could be used to precipitate gold in a similar reaction. Write the formula of the insoluble product. c. (12 points) You want to test the reaction in the lab before you head out to the ocean. Calculate how many grams of solid gold hydroxide (MW = 247.99 g/mol) would be formed if you mixed 30 mL of a 0.150 M AuCl3 solution with 0.75 g of solid NaOH (MW = 40.0 g/mol)? SHOW ALL WORK. d. (5 points) Calculate the percent yield if 0.98 g of precipitate are formed. (If you are unable to reach an answer in part c, you may use 3.0 g as the theoretical yield.) Do not enter an answer in the box below.
