Question

Which reaction represents the oxidizing behaviour of $${H_2}S{O_4}?$$

A. $$2PC{l_5} + {H_2}S{O_4} \to $$     $$2POC{l_3} + 2HCl + S{O_2}C{l_2}$$
B. $$2NaOH + {H_2}S{O_4} \to $$     $$N{a_2}S{O_4} + 2{H_2}O$$
C. $$NaCl + {H_2}S{O_4} \to NaHS{O_4} + HCl$$
D. $$2HI + {H_2}S{O_4} \to {I_2} + S{O_2} + 2{H_2}O$$  
Answer :   $$2HI + {H_2}S{O_4} \to {I_2} + S{O_2} + 2{H_2}O$$
Solution :
$$2HI + {H_2}S{O_4} \to {I_2} + S{O_2} + 2{H_2}O$$       ( $$HI$$  is oxidised to $${{I_2}}$$  ) ( $${{H_2}S{O_4}}$$  is reduced to $${S{O_2}}$$  )
