Redox Titration Lab Sheet.
Pre lab
1. After reading through the background section, define the following: (2.5 pts each)
a. oxidation
b. reduction
2. Using the boxes under the equation, place an O for the element in this reaction that is
being oxidized and place an R for the element that is being reduced. (5 pts)
5Fe2+(aq) + Mn+7O4-(aq) + 8H+ → 5Fe3+(aq) + Mn2+(aq) + 4H2O
3. How many electrons are lost by iron in the following half reaction? (2.5 pts)
5Fe2+(aq) →5Fe3+(aq) + 5e-
4. How many electrons are gained by manganese in the following half reaction? (2.5 pts)
Mn+7O4-(aq) + 5e- → Mn2+(aq)

Calculations
1. In part 1 you found the mass of oxalic acid. You will need the molar mass of this acid.
If the formula is C2O4 what is the molar mass? Show your work. (5 pts)
2. Part 3 Step 1 asks you to find the moles of oxalic acid used in each trial. Remember,
to find the moles divide the mass by the molar mass. Be sure to show your work in
the table. (5 pts)
Trail Number Mass of oxalic acid (given in Moles of oxalic acid
lab) Mass (g) / molar mass (from
above)
