    Why Aren't There Examples of Redox Reactions with 3 Half Reactions in Textbooks?

    KBrO2 + KI + HBr ---> KBr + I2 + H2O eq1 KBrO2 ---> KBr 4e- + 4H+ +KBrO2 ---> KBr + 2H2O eq2 2KI ---> I2 + 2K+ + 2e- 4KI ---> 2I2 + 4K+ + 4e- eq3 HBr ---> KBr K+ + HBr ---> KBr + H+ since the charges in eq3 are +1=+1 you don't have to multiply this equation by 4 do you...
