\( \mathrm{H}_{2} \mathrm{SO}_{4} \) cannot be used for obtaining \( \mathrm{HBr} \) from \( \mathrm{KBr} \) because:
(1) \( \mathrm{HBr} \) oxidises \( \mathrm{H}_{2} \mathrm{SO}_{4} \).
(2) \( \mathrm{HBr} \) reduces \( \mathrm{H}_{2} \mathrm{SO}_{4} \).
\( \mathrm{P} \)
(3) \( \mathrm{HBr} \) undergoes disproportionation.
(4) \( \mathrm{KBr} \) reacts very slowly.
