What is the change in oxidation state of manganese in the reaction MnO4- + 8H+ +

What is the change in oxidation state of manganese in the reaction MnO4- + 8H+ + 5e- → Mn2+ + 4H2O? (2023)

What is the change in oxidation state of manganese in the reaction MnO4- + 8H+ + 5e- → Mn2+ + 4H2O? (2023)

Step 1: Identify the oxidation state of manganese in MnO4-. Manganese has an oxidation state of +7 in this compound.
Step 2: Identify the oxidation state of manganese in Mn2+. Manganese has an oxidation state of +2 in this ion.
Step 3: Calculate the change in oxidation state by subtracting the final oxidation state (+2) from the initial oxidation state (+7).
Step 4: The change in oxidation state is +7 - +2 = +5.
Step 5: Since the oxidation state decreases from +7 to +2, this indicates that manganese is being reduced.
