1 Lesson 5: Balancing Redox Equations
UNIT 7: Lesson 5: Balancing Redox Equations

2 Example Balance Os + IO3- → OsO4 + I2 (in acidic solution). Step 1: Break the equation into two half-reactions. Step 2: Balance each half-reaction. Step 3: Multiply the half-reactions by whole numbers in order to cancel out the electrons. Step 4: Add the two half-reactions. 20 min

3 Brain Break! SUMoku!

4 Your Turn! Balance MnO4- + C2O42- → MnO2 + CO2 in basic solution. (Hint: Convert to basic as your final step.) 20 min

5 Homework: Pg. 207 #24 (a, f, o) 5 min
