A" " 0.2g sample , which is mixture of NaCl, NaBr and NaI was dissolved in water and excess of AgNO_(3) was added. The precipitate containing AgCl,AgBr and AgI was filtered, dried and weighed to be 0.412g . The solid was placed in water and treated with excess of NaBr , which converted all AgCl into AgBr . The precipitate was then weighed to be 0.4881 g . It was then placed into water and treated with excess of NaI , which converted all AgBr into AgI . The precipitate was then weighed to be 0.5868 g . What was the percentage of NaCl, NaBr and NaI in the original mixture :

A mixture of sodium chloride(NaCl) and anhydrous sodium carbonate (Na_(2)CO_(3)) has a mole ratio, 2:1 . It is dissolved in water and treated with BaCl_(2) solution. The mass of BaCO_(3) precipitated is 197 gm. Calculate the mass (in gm) of NaCl in the mixture.

1.0 g a of moist sample of a mixture of KCl and KClO_3 was dissolved in water and made up to 250mL . 25 " mL of " this solution was treated with SO_2 . The chlorate was reduced to chloride and excess of SO_2 was removed by boiling. The total chloride was precipitated as AgCl . The weight of the precipitate was 0.1435 g . In another experiment, 25 " mL of " the original solution was heated with 30 " mL of " 0.2 N solution of ferrous sulphate, and the unreacted ferrous sulphate required 37.5 " mL of " 0.08 N solution of an oxidising agent for complete oxidation. Calculate the molar ratio of the chlorate to the chloride in the given mixture Fe^(2+) reacts with ClO_3^(ɵ) according to the equation. ClO_3^(ɵ)+6Fe^(2+)+6H^(o+)toCl^(ɵ)+6Fe^(3+)+3H_2O
