Question:

What is a complete ionic equation for the reaction between {eq}Pb(NO_3)_2 {/eq} and NaI?

Complete and Net Ionic Equation:

A molecular equation is a default equation for representing the chemical change occurring when two or more substances are reacting.

In the case of an ionic reaction, the reaction may be represented by showing all the ions that would be present in the aqueous solution.

Such an equation is called a complete ionic equation and shows us the behavior of ions in the solution using which we can write the net ionic equation as well.

  • The molecular equation for the reaction is:

{eq}Pb(NO_{3})_{2} (aq) + 2NaI (aq) \rightarrow PbI_{2} (s) + 2NaNO_{3}(aq) {/eq}

  • Thus, the complete...
