Metal displacement oxidation number
« on: September 05, 2024, 09:44:45 AM »
In a single metal displacement, the more reactive metal would displace the less-reactive metal (in an ionic compound). Let A and B be metals while C be non-metal, where A is more reactive than B. The single displacement model will be like this:
A + BC --> AB + C

What if metal A has more than common oxidation states, like Fe? What will the product be?
Fe + CuCl2 --> FeCl2 + Cu
OR
Fe + CuCl2 --> FeCl3 + Cu

Thank you.

The only way to predict is to check redox potentials in tables to see where the oxidation stops (or if it will even start).

Second option is not a balanced equation, so that's also something to consider.
