Definition and Properties of Salt

How do impurities affect the smoothness and overall appearance of salt crystal surfaces during the crystallization process?

• Impurities disrupt the crystal lattice structure, leading to irregular crystal growth and rough surfaces.

• Impurities make the crystal growth more uniform and regular.

• Impurities enhance the smoothness of salt crystal surfaces during crystallization.

• Impurities have no effect on the crystal lattice structure.

State the definition of salt

• Salt is a covalent compound. Salt can be produced from the neutralization reaction between acid and base.

• Salt is an ionic compound. Salt can be produced from the reaction between a base and water.

• Salt is an ionic compound. Salt can be produced from the neutralization reaction between acid and base.

• Salt is an ionic compound. Salt can be produced from the reaction between two acids.

What are the characteristics of the surface, sides, and vertices of salt crystals?

• Has flat surfaces, straight sides, and sharp vertices.

• Has rough surfaces, jagged sides, and rounded vertices.

• Has bumpy surfaces, uneven sides, and rounded vertices.

• Has wavy surfaces, curved sides, and blunt vertices.

Why do crystals of the same salt have the same basic geometric shape regardless of their size?

• Due to crystal lattice arrangement of atoms or molecules in the salt that determines the basic geometric shape, which remains consistent across crystals of the same salt.

• Due to surfaces at which the crystals form impacts their shape

• Due to size of the crystals determines their basic geometric shape

• Due to color of the crystals influences their shaped
