0.1170g of an organic compound on heating with conc. `HNO_3 and AgNO_3` in a carius furnace gave 0.42g of silver chloride. Find the percentage of chlorine in the organic compound.

Text Solution

Verified by Experts

Mass of organic compound = 0.1170 g
Mass of silver chloride formed = 0.42 g
1 mol of AgCl =35.5g of chlorine
143.5g AgCl `=(35.5)/(143.5) xx 0.42"of g chlorine"`
0.1170 g of organic compound contain `=(35.5)/(143.5) xx (0.42)/(0.1170)"of g chlorine"`
100g of the organic compound will contain `=(35.5)/(143.5) xx (0.42)/(0.1170)xx 100=88.80% `
