Question

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   % (Nearest integer).

(Given: Molar mass of Ag is 108 and Br is 80 )

Canvas Classes · Accepted Answer

Step 1: Recall Carius Method for Bromine Estimation

In the Carius method, the organic compound is heated with fuming  and  in a sealed tube. Bromine is converted to AgBr:

Step 2: Determine Molar Masses

- Molar mass of  = 108 + 80 = 188 g/mol
- Atomic mass of Br = 80 g/mol

Step 3: Calculate Mass of Bromine

Each mole of  contains one mole of Br:

Step 4: Calculate Percentage of Bromine

Mass of compound = 0.25 g

The question asks for the answer as :

So the answer to nearest integer is
