The precipitation reaction between 25.0 mL of a solution
Chapter 4, Problem 31P(choose chapter or problem)
The precipitation reaction between \(25.0 mL\) of a solution containing a cation (purple) and \(35.0 mL\) of a solution containing an anion (green) is depicted below (with ions shown as spheres and solvent molecules omitted for clarity).
Given the following choices of reactants, write balanced totalionic and net ionic equations that best represent the reaction:
\(\mathrm{KNO}_{3} \text { (aq) } \mathrm{CuCl}_{2}(\mathrm{aq}) \rightarrow\)
\(\mathrm{NaClO}_{4}(\mathrm{aq}) \mathrm{CaCl}_{2}(\mathrm{aq}) \rightarrow\)
\(\mathrm{Li}_{2} \mathrm{SO}_{4}(\mathrm{aq}) \mathrm{AgNO}_{3}(\mathrm{aq}) \rightarrow\)
\(\mathrm{NH}_{4} \mathrm{Br}(\mathrm{aq}) \mathrm{Pb}\left(\mathrm{CH}_{3} \mathrm{COO}\right)_{2}(\mathrm{aq}) \rightarrow\)
If each sphere represents \(2.5 \times 10^{-3} \mathrm{~mol}\) of ion, find the total number of ions present.
What is the mass of solid formed?

ANSWER:
Solution 31P:
Here, we are going to find out the best representation of the reaction which is depicted in the figure.
Step 1:
A molecular equation is defined as a chemical equation where it is showing the complete, neutral formulas for every compound in a reaction.
A complete ionic equation is defined as a chemical equation where it is showing all of the species as they are actually present in solution.
A net ionic equation is defined as an equation showing only the species that actually change
during the reaction.
A spectator ions : The ions in the solution which are appear unchanged on both sides of the equation. These ions are called spectator ions because they do not participate in the reaction.
