SOLVED: A sample of phenol glycerol injection was diluted with water andan aliquot was taken and reacted with excess bromine generated frompotassium bromide and potassium bromate solutions. The excessbromine remaining after reaction was reacted with potassium iodideand the liberated iodine was titrated with sodium thiosulphate. Ablank titration was carried out where the same quantity of brominewas generated as was used in the titration of the dilutedinjection, potassium iodide was then added and

A 3.650-g sample containing bromate and bromide was dissolved in sufficient water to give 250.0 mL . After acidification, silver nitrate was introduced to a 25.00-mL aliquot to precipitate AgBr , which was filtered, washed, and then redissolved in an ammoniacal solution of potassium tetracyanonickelate(II): Ni(CN)4^2-+2 AgBr(s) →2 Ag(CN)2^-+Ni^2++2 Br^- The liberated nickel ion required 26.73 mL of 0.02089 M EDTA. The bromate in a 10.00-mL aliquot was reduced to bromide with arsenic(III) prior t
