The ore is dissolved in hot, concentrated acid and passed over a reducing agent so that all the antimony is in the form Sb3 (aq). The sba (aq) is completely oxidized by an aqueous solution of Bros (aq). Complete and balance the equation for this reaction in acidic solution. Sb Bro, Sb

Explanation / Answer

Ans 11.11

Lets use oxidation number method to balance this reaction

BrO3- ---> Br-

Br has changed from +5 oxidation state to -1

This will require addition of 6 e- in left side . Reactant side has 3 oxygen atoms so add 3H2O in right side

BrO3- + 6e- ---> Br- + 3H2O

Add 6H+ in left side to balance the hydrogen

BrO3- + 6e- +6H+ ---> Br- + 3H2O

This is our first half reaction .

Now lets see antimony.

Sb+3 ---> Sb+5

It has changed from +3 to +5.

Add 2 electrons in right side and multiply the whole reaction by 3 so that the electrons become 6 and can be cancelled out with our first half reaction.

3Sb+3---> 3Sb5+ + 6e-

This is our second half reaction.

Now add both the half reactions, and cancel out electrons from left and right side

BrO3- + 3Sb+3 + 6H+ ---> Br- + 3Sb+5 + 3H2O

So this is our balanced redox reaction in acidic medium
