A sample of soluble salts weighs 1.200g and contains chloride, bromide, and iodide. With AgNO3 a ppt is obtained which weighs 0.4500g on heating this ppt in Cl2 gas, the AgBr and AgI are converted to AgCl, and the ppt then weighs 0.3300g. A similar sample, when treated with palladous chloride, ppt only PdI2, and this ppt weighs 0.900g. Find the approximate percentages of chlorine, bromine, and iodine in the original sample.
