The net ionic equation is given as:
Pb²⁺ + 2Br⁻ → PbBr₂(s)
What is the reaction between Pb(NO₃)₂ and KBr?
Lead(II) nitrate react with potassium bromide to produce lead(II) bromide and potassium nitrate.
Pb(NO₃)₂ (aq) + KBr (aq) → PbBr₂ (s)+ KNO₃ (aq)
It is an unbalanced reaction. So, we need to balance it, which gives,
Pb(NO₃)₂ + 2KBr → PbBr₂ + 2KNO₃
What is a net ionic equation?
The chemical equation known as the net ionic equation only displays the substances that are directly involved in the chemical process.
Pb²⁺ + 2NO₃⁻ + 2K⁺ + 2Br⁻ → PbBr₂ + 2K⁺ + 2NO₃⁻
The ions with identical moles on both sides are cancelled in the net ionic equation. Therefore the net ionic equation will become,
Pb²⁺ + 2Br⁻ → PbBr₂ (s)
