presented by Macmillan Learning The quantity of antimony in a sample can be determined by an oxidation-reduction titration with an oxidizing agent. A 6.47 g sample of stibnite, an ore of antimony, is dissolved in hot, concentrated HCl(aq) and passed over a reducing agent so that all the antimony is in the form Sb*(aq). The Sb*(aq) is completely oxidized by 35.0 mL of a 0.105 M aqueous solution of KBRO, (aq). The unbalanced equation for the reaction is BrO, (aq) + Sb³*(aq) Br (aq) + Sb³* (aq) (unbalanced) Calculate the amount of antimony in the sample and its percentage in the ore. mass of antimony: percentage of antimony: Question Source: McQuarrie, Rock, And Gallogly 4e - General Chemsitry | Publisher: University Science Books

Crystal Structures

Solids are present all around us. They have different properties and applications. Diamond and graphite are two well-known solids. Diamond is the hardest material in the world and is used in making jewelry. Graphite on the other hand is soft. The lead of your pencil is graphite. Why are they so different in appearance and properties despite the fact they are chemically the same? Both are allotropes of carbon. The answer lies in the structure, the way constituent particles are arranged in the solids.
