Question

51 3. Hydroxylammonium chloride reacts with iron(lIl) chloride, FeCl, in solution to produce iron(I) chloride, HCl, H,O, and a compound of nitrogen. It was found that 2.00g of iron(II) chioride reacted in this way with 31.0 mL of 0.200M hydroxylammonium chloride. Suggest a possible formula for the compound of nitrogen so produced. This should be a known nitrogen compound. 4. Arsenic(II) oxide, As,O3, can be titrated with potassium bromate in aqueous solution to produce potassium bromide and arsenic acid, H,AsO,. A mixture contained arsenic(ITI) oxide and arsenic(V) oxide, As,Os, and it was found that 1.000g of this mixture could be titrated in this way with 21.00 mL of 0.1000M KBrO,. What is the percentage by weight of each oxide of arsenic in the mixture?
