a binary solution A+B- has a structure with B-ions constituting the lattice and A+ ions occupying 25% tetrahedral holes. what is the formula of the solid?
Let no. of unit cells = n.Then , no of Tetrahedral voids = 2n . 25% ot this = 2n/4 = n/2.
So the required formula is An/2Bn or AB2 . Hope that helps.
