The ions present in the solution of [tex]{\text{Pb}}{\left( {{\text{N}}{{\text{O}}_{\text{3}}}} \right)_{\text{2}}}[/tex] are [tex]\boxed{{\text{P}}{{\text{b}}^{2 + }},\;{\text{NO}}_3^-}[/tex] and both these ions are present in the aqueous phase.
Further explanation:
Chemical formula:
It provides complete information about the elements and their respective proportions in any particular compound.
Following are the steps to write the chemical formula of a compound:
1. The letter symbols of cations and anions are to be written.
2. Charges on cation and anion are to be identified. Generally, group 1 elements have +1 charge, group 2 elements have -2 charge, Group 16 elements have -2 charge, group 17 elements have -1 charge.
3. The total positive and negative charge needs to be balanced out. This is done by writing the charge on anion as a subscript for cation and the charge on cation as a subscript for anion.
[tex]{\text{Pb}}{\left( {{\text{N}}{{\text{O}}_{\text{3}}}} \right)_{\text{2}}}[/tex] is formed from one [tex]{\text{P}}{{\text{b}}^{2+}}[/tex] and two [tex]{\text{NO}}_3^-[/tex] ions. (Refer to the structure in the attached image). So when it is present in the solution, its constituent ions are produced and therefore [tex]{\text{P}}{{\text{b}}^{2+}}[/tex] and [tex]{\text{NO}}_3^-[/tex] are the ions present in the solution of [tex]{\text{Pb}}{\left( {{\text{N}}{{\text{O}}_{\text{3}}}} \right)_{\text{2}}}[/tex]. Both these ions are present in the aqueous phase.
