The molecular equation :
MgI₂(aq) + Pb(NO₃)₂(aq) → Mg(NO₃)₂(aq) + PbI₂(s)
The net ionic equations
Pb²⁺(aq) + 2I⁻(aq) → PbI₂(s)
<h3>Further explanation</h3>
Given
Word equation
Required
The molecular equations and the net ionic equations
Solution
The chemical equation can be expressed in terms of:
- word equation
- skeleton equation
- balanced equation
The equation of a chemical reaction can be expressed in the equation of the ions
When a spectator ions are removed, the ionic equation is called the net ionic equation
A molecular equation is a chemical equation that has been balanced and is written in molecular (not ionic) form
The molecular equation :
MgI₂(aq) + Pb(NO₃)₂(aq) → Mg(NO₃)₂(aq) + PbI₂(s)
the ionic equation :
Mg²⁺ +2I⁻ + Pb²⁺ + 2NO₃⁻ → Mg²⁺ + 2NO₃⁻ + PbI₂
the net ionic equations
Pb²⁺(aq) + 2I⁻(aq) → PbI₂(s)
