50 mL of 0.1 M solution of a salt reacted with 25 mL of 0.1 M solution of sodium sulphite. The half reaction for the oxidation of sulphite ion is: \[SO_{3}^{2-}(aq)+{{H}_{2}}O(l)\to SO{{_{4}^{2-}}^{~}}(aq)+2{{H}^{+}}(aq)+2{{e}^{-}}\] If the oxidation number of metal in the salt was 3, what would be the new oxidation number of metal?
