Using Kröger-Vink notation, write the defect chemical equation for mixing FeO into Fe2O3

Using Kröger-Vink notation, write the defect chemical equation for mixing FeO into Fe₂O₃

Expert Solution

Dear friend your answer is by using the Kroger-Vink notation for FeO in Fe2O3 is

1. vacancy creation doesn’t change site balance

2. Keep in mind that we have strongly ionic species in this example; charges are involved

3. Placing a Fe2+ ion on a Fe3+ site gives a net -1 charge on the site

4. A vacancy must be created in order to preserve charge neutrality and maintain site relation. This is a “trick” that you will have to learn.

Thank you.

a sample of iron ore (m=0,330g)consisting of a mixture of FeO and Fe2O3 was dissolved in dilute sulfuric acid and titrated with a potassium permanganate solution containing 0.0200g of KMnO4 per litre, and required 20,3 mL for complete reaction. The second sample of iron ore (m=0,370g)was dissolved in dilute sulfuric acid solution and fe3+ is reduced to fe2+ then titrated with the same potassium permanganate solution. 42,6mL was required for the second titration. Calculate the mass of each iron oxide...
