Put it under the flame of a bunsen burner, and if it turns bright orange, then it is NaCl. Also, if you put some Silver Nitrate (AgNO4) into it, and a cloudy white precipitate comes out, you also know it is NaCl. and it will be safe to taste!
for the conductance of electricity freely moving ions and electrons are necessary. But in NaCl (in solid form) Na positive ion and Cl negative ion are held together by strong electrostatic force and there is no freely moving ion in NaCl (in solid state) therefore NaCl does not conduct electricity in solid form.
true
NaCl in frozen water NaCl in BaI2 (assuming BaI2 has the greater amount)
Sodium chloride (NaCl) is a solid.
NaCl
Solid sodium chloride is not an electrical conductor.
If you think to NaCl(s) the meaning is solid sodium chloride.
Salt is a solid
The standard enthalpy of formation for NaCl solid is: -411,12 kJ/mol at 25 0C.
Solid NaCl is not an electrolyte; the saline solution or the molten NaCl are electrolytes.
(s) is solid.
It is an ionic crystalline solid
