Is sodium chloride soluble in HCl?

Answer 1

Of course it is. By HCl, you must mean an aqueous solution (i.e. hydrochloric acid). Remember that the acidity of hydrochloric acid comes from the stability of the chlorine anion in a polar solvent. Aqueous HCl exists as Cl- ions and H3O+ ions solvated by water molecules. Just the same, NaCl will also dissolve in the solution. The ions will separate, attracted differently by the separated partial charges on the water molecule--the lone pairs of electrons on the oxygen atom, and the partial positive charge on the protons. Naturally, though, the solubility of salt will be lower in a solution of acid than in pure water. If you were to add NaCl to a highly concentrated solution of hydrochloric acid, I don't think very much would dissolve since the acidic protons would be more strongly bound to the water molecules than the sodium cations would be. That's probably a good thing, because otherwise the solution would begin to evolve hydrogen chloride gas: breathe that in, and your mucous membranes are toast.

Answer 2

Yes, it is soluble in the water solution of HCl.

Answer 3

The term soluble is inadequate here; these compounds in solution are totally miscible.

Answer 4

Sodium chloride is dissociated in water; hydrochloric acid is not obtained.

Answer 5

Any reaction occur between HCl and NaCl.

Answer 6

No, both have the same anion Cl-

Answer 7

No
