Question

Name any five crystalline salts giving their chemical name and chemical formula?

Answer 1

1. Sodium Chloride => NaCl
2. Potassium Dichromate => K₂Cr₂O₇
3. Calium Chloride => CaCl₂
4. Sodium Bisulfate => NaHSO₄
5. Copper Sulfate => CuSO₄

Answer 2

NaCl= Sodium Chloride

Na2O=Sodium Oxide

CuSO4=Copper sulfate

CsCl=Caesium Chloride

ZnS=Zinc Sulfide

crystalline substances are those which contain periodic arrangement of lattice points.They contain some parallel planes from which reflection occurs.This occurs according to Bragg's law.They may have different close packed structure. e.g. BCC,FCC,simple cube. crystals are often used in pseudoscientific practices such as crystal therapy, and, along with gemstones, are sometimes associated with spellwork in Wiccan beliefs and related religious movements
