Consider the reaction : H 2 SO 3 aq + Sn aq 4 + + H 2 O l ⁡ → Sn aq 2 + + HSO 4 aq - + 3 H aq + Which of the following statements is correct ?

Question

TestHub · Accepted Answer

Identify oxidation states of all elements in Redox Reaction

$H_{2} {\overset{+ 4}{SO}}_{3} + \overset{4 +}{Sn} + H_{2} O (l) \to \overset{2 +}{Sn} + H \overset{+ 6}{{SO}_{4}^{-}_{}} + 3 H_{}^{+}$

S is changing the oxidation state from (+4) to (+6). i.e H₂SO₃is a Reducing agent because it undergoes oxidation.
