Question

Balance the given reaction in acidic medium.

Answer 1

_________________HEY MATE__________________

HERE IS YOUR ANSWER !!! SRRY I TOOK SO LONG TO ANSWER -

H2O2(aq) + Fe2+(aq) ----------> Fe3+(aq) +H2O(l)  {IN ACIDIC MEDIUM}

THE ANSWER IS - H2O2 + 2 H+ + 2Fe2+ ---> 2 H2O + 2Fe3+  

via ionic half reactions , I GOT -

Fe2+ ---> Fe3+ + 1e-

as we are oxidizing ferrous ion to ferric ion - hence the loss of the electron; something has to be reduced i.e. h202

H2O2 + 2 H+ + 2 e- ---> 2 H2O  

now since we consume 2 electrons in the H2O2 half reaction we need to double the first reaction to off set the electrons and combine  

H2O2 + 2 H+ + 2 e- + 2Fe2+ ---> 2 H2O + 2Fe3+ + 2e-  

finally you see the 2e- on both sides of the --> so you remove them to show  

H2O2 + 2 H+ + 2Fe2+ ---> 2 H2O + 2Fe3+

DO MARK IT AS BRAINLIEST IF DESERVABLE ...

Hope its helpful
