What is the oxidation state of S in the sulphur containing product of the following reaction? SO 3 - 2 ( aq )   +   Br 2 ( l )   +   H 2 O   →

Step-by-step solution

This is a redox reaction in which Sulphur will oxidised and Bromine will reduce according to the following reaction. SO 3 - 2 ( aq )   +   Br 2 ( l )   +   H 2 O   → SO 4 - 2 ( aq )   +   Br - +   H + Balanced reaction will be SO 3 - 2 ( aq )   +   Br 2 ( l )   +   H 2 O   → SO 4 - 2 ( aq )   +   2 Br - ( a q ) + 2 H + The sum of oxidation states of all elements in a compound is always zero or equal to total charge on ion.
