A one litre flask is full of brown bromine vapours. The intensity of brown colour of vapours will not decrease appreciably on adding to the flask some
A.
pieces of marble
B.
animal charcoal powder
C.
carbon tetrachloride
D.
carbon disulphide
Answer :
pieces of marble
Solution :
Bromine is soluble in $$CC{l_4}$$ and $$C{S_2}.$$ Animal charcoal also adsorbs on bromine water. But marble has no action with $$B{r_2}.$$ So, after adding marble piece to the flask, there will be no change in the intensity of brown colour.
