C2 T13HW Question 15 - CHALLENGE HomeworkUnanswered Fill in the Blanks Antimony (Sb) is a chemical element that is often used to make alloys with lead and tin. The quantity of Sb in a sample can be determined by an oxidation-reduction titration using a sample of Sb ore as the analyte and an oxidizing agent as the titrant. Consider a reaction in which a 9.47 g sample of stibnite, an ore of Sb, is dissolved in hot, concentrated HCl(aqHCl(aq) and...
