Answer to Question #349738 in General Chemistry for Becky

Question

Write the balanced NET ionic equation for the reaction when Pb(NO₃)₂ and KI are mixed in aqueous solution. If no reaction occurs, simply write only NR.

Answer 1

Solution:

Molecular equation:

Pb(NO₃)₂(aq) + 2KI(aq) → PbI₂(s) + 2KNO₃(aq)

Total ionic equation:

Pb²⁺(aq) + 2NO₃⁻(aq) + 2K⁺(aq) + 2I⁻(aq) → PbI₂(s) + 2K⁺(aq) + 2NO₃⁻(aq)

Net ionic equation:

Pb²⁺(aq) + 2I⁻(aq) → PbI₂(s)
