A 0.5485 g solid mixture have only ferrous chloride hexahydrate and ferrous ammonium sulfate hexahydrate. dissolved in 1M sulphuric acid get oxidized to Fe3+ with hydrogen peroxide, and get precipitated with cupferron. ( ferric cupferron complex was ignited to produce 0.167 g of ferric oxide, Fe2O3 ). Determine the weight % of Chlorine in original sample.
