Question

If the composition of the solid solutions dependence is linear then which of the following law is obeyed?

(a) Mendeleev’s law

(b) Stock Barger’s law

(c) Bridgeman’s law

(d) Vegard’s law

I had been asked this question in unit test.

My query is from Survey of Techniques and their Applications to Solids topic in division Preparative Methods of Solid State Chemistry

Answer 1

Right option is (d) Vegard’s law

For explanation: for the solid solutions the composition dependence if linear then Vegard’s law is obeyed, deviation from this law often occur in metallic solid solutions and when they occur can usually be ascribed to a structural feature in the solid solutions.
