Question

Write the following equation as a balanced ionic equation

Zn(s) + Pb(NO₃)₂ (aq) --> Zn(NO₃)₂ (aq) + Pb (s)

I don't understand how to write it in the ionic equation form! Thanks!

Answer 1

Hey there!:

Molecular equation is:

Zn (s) + Pb(NO3)2 (aq) --> Zn(NO3)2 (aq) + Pb (s)

To get complete ionic equation, break aqueous components into respective ions,so the complete ionic equation is

Zn (s) + Pb²⁺ (aq) + 2 NO³⁻(aq) --> Zn²⁺ (aq) + 2 NO³⁻ (aq) + Pb (s)

To get net ionic equation, remove the common ions from both sides

So, the net ionic equation is:

Zn (s) + Pb²⁺ (aq) --> Zn²⁺ (aq) + Pb (s)

Hope that helps!
