There is NO real chemical reaction when NaCl dissolves, it is only ionized (split into ions):
NaCls + [H2Oliq] --> Na+aq + Cl-aq + [H2Oliq]
When sodium chloride dissolves in water, the ions in the crystal (Na+ and Cl-) enter the aqueous phase, Na+(aq) and Cl-(aq).
It is called subtracting reaction.
It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.
This is an example for the dissociation in water of a ionic compound.
no chemical reaction takes place when sodium hydroxide dissolves in water. but the Na+ and OH- ions gets surrounded by water molecules
No. Sodium chloride in water dissolves into its individual Na+ ions and Cl- ions due to the polarity of the water molecule. This is not a bonding between water and sodium chloride. In fact there is no chemical reaction at all taking place. The dissolving of the sodium and chloride ions by water is a physical change, and can be reversed by letting the water evaporate.
When sodium chloride dissolves in water, the ions in the crystal (Na+ and Cl-) enter the aqueous phase, Na+(aq) and Cl-(aq).
This is a dissociation reaction.
It is called subtracting reaction.
In solid sodium chloride, the ions are fixed in place in a giant lattice. When it dissolves in water the ions separate and become free to move around.
It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.
NaCl (s) + H2SO4 (l)-------> HCl (g) + NaHSO4 (s)
Yes.
This is an example for the dissociation in water of a ionic compound.
Basically,when they are treated,then the following reaction takes place: RCOOH+NaOH-------RCOONa+H2O
no chemical reaction takes place when sodium hydroxide dissolves in water. but the Na+ and OH- ions gets surrounded by water molecules
Dissolving salt in water is an example of a physical change. Although the ions of sodium and chlorine separate when the salt dissolves, no chemical reaction takes place.
