S + 02 --> SO2
2SO2 + O2 <--> 2SO3 (at 1atm. pressure, 450'C nd vanadium (V) oxide catalyst)
SO3 + H2SO4 --> H2S2O7
H2S2O7 + H2O --> 2H2SO4

Hello ppl,
i have this question from the Igcse chem guide topic11 on pgno.56.
For the followin redox reaction write half equations, showing the electron transfer. Then identify the change which is oxidation an the reactant which is the reducing agent. Give reasn for each ans.
i knw the answers n the 1st part of forming an equation is not the prob. i have a prob wid the 2nd part, i'm not able to understand the explaination given in the ans behind. It says I- is the reducing agent but i think it is wrong.
If u think the ans given is right then plz explain me.
Hope u got my question!!

Hey buzywidbizworld
first of all the answer given at the back is right!
now the explanation:
the equation for Iodine is : 2I- - 2e- ---> I2
now as u can see the iodine is losing electrons and is thus oxidised(oil rig)
Whenever a substance is oxidised, it acts as a reducing agent
reason: because it is losing the electrons, which will later be gained by Cl to be reduced, therefore it is aiding Chlorine in getting reduced.
Do u get what i am trying to say?
Basically, always remember that whichever ion gets reduced acts as the oxidising agent and whichever gets oxidised acts as a reducing agent.
Tell me if you still didn't understand

Write an ionic equation for the precipitation of the insoluble salt, silver(I) chloride.
answer this if ne body can!!!
