In Carius method of estimation of halogen, 0.25 g of an organic compound gave 0.15 g of silver bromide ( AgBr ) . The percentage of Bromine in the organic compound is 10^ -1 % (Nearest integer). (Given : Molar mass of Ag is 108 and Br is 80 ~g ~mol ⁻¹ )
Correct answer
0
Step-by-step solution
Mass of organic compound =0.25 ~g Mass of AgBr =0.15 ~g No. of moles of Br = No. of moles of AgBr = 0.15 188 aligned & Mass of Br = 0.15 80 188 ~g & % of Br = 0.15 80 100 188 0.25 & =25.5 % & =255 10⁻¹ % aligned
