Veterinarians use Donovan’s solution to treat skin diseasesin animals. The solution is prepared by mixing 1.00 g ofAsI3(s), 1.00 g of HgI2(s), and 0.900 g of NaHCO3(s) inenough water to make a total volume of 100.0 mL.(a) Compute the total mass of iodine per liter of Donovan’s solution, in grams per liter.(b) You need a lot of Donovan’s solution to treat an outbreak of rash in an elephant herd. You have plenty of mercury(II) iodide and sodium hydrogen carbonate, but the only arsenic(III) iodide you can find is 1.50 of a 0.100 M aqueous solution. Explain how to prepare 3.50 L of Donovan’s solution starting with these materials.
