Verified step by step guidance1
Identify the overall charge of the compound Mn(ClO4)3. Since no charge is given, assume it is neutral (charge = 0).
Determine the charge of the perchlorate ion (ClO4). The perchlorate ion has a charge of -1.
Since there are three perchlorate ions, the total negative charge contributed by the perchlorate ions is 3 × (-1) = -3.
Let the oxidation state of manganese (Mn) be x. Write the equation for the sum of oxidation states in the compound: x + 3(-1) = 0.
Solve the equation for x: x - 3 = 0, so x = +3. Therefore, the oxidation state of Mn in Mn(ClO4)3 is +3.
