Now sum the coefficients of all species in the balanced equati (Remember the coefficients that are equal to one.) The sum of the coefficients is 9) BrO3(aq) + Sb3+(aq) Br(aq) + Sb5+(aq) (acidic solution)

Explanation / Answer

48)

The reaction is split into two half reactions:

Mn(OH)2 MnO42- MnO4- MnO42-

Oxygen atoms are balanced as: oxygen atoms are in balanced state.

Mn(OH)2+2OH- MnO42-                                                                      MnO4- MnO42-

Hydrogen atoms are balanced as:

Mn(OH)2+2OH- MnO42-+4H2O

Mn(OH)2+2OH- +4OH- MnO42-+4H2O

Charge is balanced as: charge is balanced as:

Mn(OH)2+6OH- MnO42-+4H2O+5e- MnO4- +e- MnO42-

Equalizing the charges and adding both the equations as:

Mn(OH)2+6OH- MnO42-+4H2O+5e-     

5MnO4- +5e- 5MnO42-

--------------------------------------------------

Mn(OH)2+5MnO4- +6OH- 6MnO42-+4H2O

6OH- are added on the reactant side. Option C) is correct.
