2 KMnO4(aq) + 5 H2O2(aq) + 6 HCl(aq) ? 2 MnCl2(aq) + 5 O2(g) + 8 H2O (l) + 2 KCl(aq) (I Think I Balanced This right, Not positive though) Write the complete ionic equation in the space below. (hint: MnO4-is the polyatomic ion
Solution
MnO4- + 8H+ + 6e ---------------------------> Mn^2+ 4H2O..................... (1)
H2O2 ---------------------------> O2 + 2H+ +2e...................(2)
multiply (2) by 3 and add (1) & (2)
MnO4- + 3H2O2 + 2H+ ------------------------> Mn^2+ 3O2+ 4 H2O
above is the balanced ionic eqution
