Question

In the estimation of bromine, 0 . 5 g of an organic compound gave 0 . 40 g of silver bromide. The percentage of bromine in the given compound is % (nearest integer) (Relative atomic masses of Ag and Br are 108 u and 80 u , respectively).

TestHub · Accepted Answer

The estimation of halogens in organic compounds is usually done by carius method.

Percentage of Bromine $= \frac{Atomic mass of Br}{Molecular mass of AgBr} \times \frac{Mass of AgBr \times 100}{Mass of the organic compound}$

$= \frac{80 \times 0.4 \times 100}{188 \times 0.5}$

$= 34 %$
