Question -
In the reaction 2Ag+2H2SO4→Ag2SO4+2H2O+SO2 sulphuric acid acts as
Options:
A .  An oxidizing agent
B .  A reducing agent
C .  A catalyst
D .  An acid as well as an oxidant
Answer: Option A : A The sulphur in H2SO4 gets reduced from a +6 oxidation state to +4 in SO2. Also, we see that Ag0 becomes Ag+1. This shows that sulphur has gained electrons and got reduced thereby oxidizing others. So H2SO4 acts as an oxidizing agent.
