A sample is a mixture of Mohr's salt and (NH4)2SO4. A 0.5 gram sample of the mixture gave a precipitate of 0.75 grams of Barium sulphate. Calculate the percentage composition of the mixture. What weight of Fe2O3 be obtained if 0.2 grams of the mixture were ignited in air?
Dear Student,
When the mixture of mohr's salt and ammonium sulphate reacts with barium chloride, only ammonium sulphate reacts to form barium sulphate. The reaction being:
