Consider the unbalanced redox reaction.
MnO4− (aq) + Zn(s) → Mn2+(aq) + Zn2+(aq)
Balance the equation in acidic solution and determine how much of a 0.500 M KMnO4 solution is required to completely dissolve 2.85 g of Zn.
Solution 97P :
The balanced equation is :
2MnO4- + 16H + 5Zn → 2Mn2+ + 8H2O + 5Zn2+
Let’s find the number of moles of 2.85g of zinc :
Number of moles (n) =
Molar mass of zinc = 65.38 g/mol
= 0.04359 moles.
