The solution remaining after the formation of crystals is called ___________________?

Correct answer: A. Mother liquor

  • A. Mother liquor
  • B. Dilute solution
  • C. Residue
  • D. both A & B

Explanation

During crystallisation, the desired crystals separate from the solution while the remaining liquid retains dissolved solute and is called the mother liquor. It is not simply called residue, which usually means the solid left after filtration or evaporation. Students may choose both A and B because the mother liquor is a remaining solution, but it is not necessarily dilute.

About Crystalline Solids

Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
