Electrolytes dissociate when dissolved in water to produce charged particles known as ions. Copper (II) nitrate [tex]\text{Cu} (\text{NO}_3})_2[/tex] contains copper (II) ions [tex]\text{Cu}^{2+}[/tex] and nitrate [tex]\text{NO}_3^{-}[/tex] ions.
[tex]\text{Cu}(\text{NO}_3)_2 \; (aq) \to \text{Cu}^{2+}\; (aq)+ 2 \; \text{NO}_3^{-}\; (aq)[/tex]
As a strong electrolyte [tex]\text{Cu} (\text{NO}_3})_2[/tex] would dissociate completely to release the two kinds of ions. Thus indicate a complete reaction in the equation with the single-headed arrow [tex]\to[/tex].
