Briefly mention how are the substitutional and interstitial solutions different?
Substitutional solutions and interstitial solutions are two types of solid solutions.
Substitutional solutions: These are formed by substituting atoms/ molecules or ions of one substance by similar atoms, molecules or ions of other substances. For example: brass, steel etc.
Interstitial solutions: These are formed by placing atoms of one type in the voids or interstices of atoms of host lattice. For example, carbon within iron is interstitial solid solution.
