Question

What is the net ionic equation of the reaction of MgSO4 with Pb(NO3)2 ?Express you answer as a chemical equation including phases.

Answer 1

`\begin{gathered} \text{ Net Ionic Equation:} \\ SO_(4(aq))^(-2)+Pb_((aq))^(+2)\rightarrow PbSO_(4(s)) \end{gathered}`

Step-by-step explanation:

1st) It is necessary to write and balance the chemical reaction. In this step, we write the Molecular equation, including the phases of each compound:

`MgSO_(4(aq))+Pb(NO_3)_(2(aq))\rightarrow PbSO_(4(s))+Mg(NO_3)_(2(aq))`

2nd) It is very usefull to write the Complete ionic equation, to identify the ionic form of each element in the reaction. In this step it is important to write only the ionic form of elements in aqueous phase:

`Mg_((aq))^(+2)+SO_(4(aq))^(-2)+Pb_((aq))^(+2)+(NO_3)_(2(aq))^(-1)\rightarrow PbSO_(4(s))+Mg_((aq))^(+2)+(NO_3)_(2(aq))^(-1)`

3rd) Finally, we can write the Net ionic equation, canceling the ionic species that repeat on both sides of the Complete ionic equation:

`SO_(4(aq))^(-2)+Pb_((aq))^(+2)\rightarrow PbSO_(4(s))`

So, this is the Net ionic equation.
