Bromine water reacts with SO2SO_2 to form ?

A

H2OH_2O and HBr

B

H2SO4H_2SO_4 + HBr

C

HBr and S

D

S and H2OH_2O

Answer

H2SO4H_2SO_4 + HBr

Explanation

Solution

When bromine water reacts with SO2SO _{2}, it oxidises it to sulphuric acid and itself gets reduced to HBrHBr. Br2+2H2O+SO22HBr+H2SO4\underbrace{ Br _{2}+2 H _{2} O }+ SO _{2} \longrightarrow 2 HBr + H _{2} SO _{4}
