WebThe catalyst can be either iron (II) or iron (III) ions which are added to the same solution. This is another good example of the use of transition metal compounds as catalysts because of their ability to change oxidation state. For the sake of argument, we'll take the catalyst to be iron (II) ions. fisheries officer previous question paper
