What happens when table salt (NaCl) is added to water?

Answer 1

Hydration of the individual ions and formation of discrete aqua complexes, #Na^+(aq)# and #Cl^-(aq)#.

By most definitions, this is properly considered an example of chemical change, i.e. the formation of new substances, and the making and breaking of strong chemical bonds. We write #Na^+(aq)#; in solution we have the hexaqua complexes, #[Na(OH_2)_6]^+# and #[Cl(H_2O)_(4-6)]^-#.

When table salt (NaCl) is added to water, it dissociates into its constituent ions, sodium (Na+) and chloride (Cl-) ions. This process is called dissolution. The water molecules surround the individual ions and pull them apart from the crystal lattice structure of the salt. As a result, the salt dissolves in water, forming a homogeneous solution of sodium chloride ions dispersed throughout the water.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
