The Composition of a sample of wustite is `Fe _0.93 O_1.00` What percentage of the iron is present in the form of Fe (III)

The composition of a sample of Wustite is Fe_(0.93)O . What is the percentage of iron present as Fe^(3+) in total iron?

What happens when SO_2 is passed through an aqueous solution of Fe (III) salt?

The ratio Fe^(3+) and Fe^(2+) ions in Fe_(0.9)S_(1.0) is.

Iron (Il) oxide crystallise in cubic structure with unit cell edge of 5.0Å If the density of the oxide is 3.8 g cm-3 . Calculate the no. of Fe^2+ and O_2- present in each unit cell. [atomic mass of Fe=56, O=16]

F centre is an example of metal excess defect due to the presence of extra cations at interstitial sites. Zinc oxide is white in colour at room temperature, on heating it loses oxygen and turns yellow. ZnO overset("Heat")toZn^(2+)+(1)/(2)O_(2)+2e^(-) Now there is excess of zinc in the crystal and its formula becomes Zn_(1+x) O. the excess of Zn^(2+) ions move to interstitial sites and the electrons to neighbouring interstitial sites. There are many solids which are difficult to prepare in the stiochiometric composition and contain less amount of the metal as compared to stiochiometric proportion. a typical example of this type is FeO which is mostly found with a composition of Fe_(0.95) . it may actually range from Fe_(0.96) O. Q. In Fe_(0.95) O:

Q. In the crystal of Fe_(0.95) O:
