    The Question is incomplete here is the complete question " Suppose an iron atom in the oxidation state + 3 formed a complex with three hydroxide anions and three water molecules. Write the chemical formula of this complex.

    Answer:

    {Fe (OH) 3 (H20) 3}

    Explanation:

    Oxidation state is the electron gained or lost by and atom, So if iron is in + 3 state in formula it must have lost three electron.

    We know that OH posses the oxidation state of - 1 and water have zero oxidation state. SO, Let's take iron equal to y and find its oxidation state in the formula

    y + 3 ( - 1) + 3 (0) = 0

    y - 3 + 0 = 0

    y-3=0

    y = + 3

    Hence it's proved that iron has + 3 oxygen state.
