What is the primary oxidation state of manganese in potassium permanganate (KMnO4)?

What is the primary oxidation state of manganese in potassium permanganate (KMnO4)?

Step 1: Identify the chemical formula of potassium permanganate, which is KMnO4.
Step 2: Recognize that potassium (K) has an oxidation state of +1.
Step 3: Understand that oxygen (O) typically has an oxidation state of -2.
Step 4: Since there are 4 oxygen atoms in KMnO4, calculate the total oxidation state contributed by oxygen: 4 O x -2 = -8.
Step 5: Set up the equation for the overall charge of the compound, which is neutral (0): +1 (from K) + x (from Mn) + (-8) (from O) = 0.
Step 6: Solve the equation: +1 + x - 8 = 0, which simplifies to x - 7 = 0, so x = +7.
Step 7: Conclude that the oxidation state of manganese (Mn) in potassium permanganate (KMnO4) is +7.
