In anon stochiometric sample of ferrous oxide with Nacl str. The ratio

1.	In anon stochiometric sample of ferrous oxide with Nacl str. The ratio of Fe3+ to Fe2+ was found to be 0.15 calculate fraction of octahedral sites occupied by vacanies
Answer» This is a charge balancing question. Fe exists in two forms mainly Ferrous (FE2+) and Ferric (Fe3+). Let there are 100 OXYGEN ATOMS and x number of Fe3+ atoms and 96-x number of Fe2+ atoms.

This is a charge balancing question.

Fe exists in two forms mainly Ferrous (FE2+) and Ferric (Fe3+).

Let there are 100 OXYGEN ATOMS and x number of Fe3+ atoms and 96-x number of Fe2+ atoms.
