Question

what is the basic difference between congruent and incongruent melting point? ​

Answer 1

Answer:

The composition of the liquid that is formed after melting is the same as that of the solid. In incongruent melting, one of the intermediate compounds in the solid phase transforms into another solid phase compound and a liquid phase, which are both having different chemical compositions than the original composition.

Answer 2

Explanation:

Congruent melting - melting wherein a phase melts to a liquid with the same composition as the solid. Incongruent melting - melting wherein a phase melts to a liquid with a composition different from the solid and produces a solid of different composition to the original solid.
