Answer 1

Answer : The net ionic equation will be,

`Pb^(2+)(aq)+SO_4^(2-)(aq)\rightarrow PbSO_4(s)`

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The same number of ions present on reactant and product side which do not participate in a reactions.

The given balanced ionic equation will be,

`MgSO_4(aq)+Pb(NO_3)_2(aq)\rightarrow Mg(NO_3)_2(aq)+PbSO_4(s)`

The ionic equation in separated aqueous solution will be,

`Mg^(2+)(aq)+SO_4^(2-)(aq)+Pb^(2+)(aq)+2NO^(3-)(aq)\rightarrow PbSO_4(s)+Mg^(2+)(aq)+2NO^(3-)(aq)`

In this equation,
`Mg^(2+)\text{ and }NO_3^-` are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

`Pb^(2+)(aq)+SO_4^(2-)(aq)\rightarrow PbSO_4(s)`
