This depends on this "something".
No reaction.
Any reaction occur.
NaHCO3 + HCl → NaCl + H2CO3
NaCl salt is formed and H2 gas is given off
Any reaction; a solution containing ions of H+, Na+ and Cl- is obtained.
When NaCl is added to water, you would observe that it dissolves quite readily.
Nothing happens. It is still NaCl and KOH.
the concentration of Cl- increase (common ion), but the pH of the solution remain same.
To decrease melting point of NaCl
NaCl is added to water when a saline water solution is necessary; NaCl is dissociated in water: NaCl -------------------Na+ + Cl-
Any reaction between NaCl and H.
Ammonia gas will be evolved. The chemical reaction is :NH4Cl + NaOH --> NH3 (g) + NaCl + H2O
Nothing. NaCl creates a reverse reaction to H2O.
Yes. When NaCl is added to water, it forms a solution, which is a homogeneous mixture.
