u) u) 00 B. Basic conditions Add 2 mL of sodium hydroxide to 1 mL of potassium permanganate. Then add hydrogen peroxide. From the change in color identify the manganese product. It isMn Oz Additional evidence indicates that the product from hydrogen peroxide must be 2 Complete the redox reaction and balance it under basic conditions: 8 0 0.8 oa 88L 3 Zl LSL 8 9p'L apusurua uIZ Ieyn un aldurs to 8 CO CO CO CO Co gz.L 8 2 8 9 'JIdures aquuale“ Jo sa 0 'g 8 $9.9 2 8 9 lt'9 9 0 0 8 61.9 Z' paloolloo sea Jo aumpa aqurExplanation / Answer
Your data is is disordered, so I'm gonna answer just the question of the balance:
We have Mn and H2O2 in basic medium so:
MnO4- + H2O2 --------> MnO2 + O2
(2H2O + MnO4- + 3e- --------> 4OH- + MnO2)*2
(2OH- + H2O2 ------------> O2 + 2e- + 2H2O)*3
4H2O + 2MnO4- + 6e- --------> 8OH- + 2MnO2
6OH- + 3H2O2 ------------> 3O2 + 6e- + 6H2O
2MnO4- + 3H2O2 ------------> 2MnO2 + 3O2 + 2OH- + 2H2O
Hope this helps
