A non stoichiometric compound Fe

7

S

8

consist of iron in both Fe

+2

and Fe

+3

form and sulphur is present as sulphide ions. Calculate cation vacancies as a percentage of Fe

+2

initially present in the sample. (Express your answer as

x

100

% and you should write x as answer)

Answer 2

Answer:

11

Explanation:

Let the fraction of Ag2+ is X then Ag+= 1.8-x.

Now using charge balence equation

2*x +1*(1.8-x) =2, from where x=0.2

Then percentage of Ag2+= 0.2/1.8*100=11.1%
