Question
**Limiting Reagent Educational Activity**

In this exercise, you will explore the concept of limiting reagents using a chemical reaction between lead(II) nitrate \((\text{Pb(NO}_3)_2)\) and potassium iodide \((\text{KI})\). 

**Chemical Reaction:**

\[
\text{Pb(NO}_3)_2 \, \text{(aq)} + 2 \, \text{KI (aq)} \rightarrow \text{PbI}_2 \, \text{(s)} + 2 \, \text{KNO}_3 \, \text{(aq)}
\]

**Scenario:** An aqueous solution of Pb(NO\(_3\))\(_2\) and KI are mixed together. Suppose KI is the limiting reagent.

**Instruction:**

Drag the purple words into the gray boxes below the ions to identify the type of calculation needed to find the concentration of each ion.

**Ions and Boxes:**

1. I\(^-\)
2. K\(^+\)
3. NO\(_3^-\)
4. Pb\(^{2+}\)

**Purple Words to Drag:**

- mixing only
- limiting reagent, none left
- excess reagent, some left over
- limiting reagent, none left

**Concept:** By determining the limiting reagent, you can predict which reactant will be completely consumed and which will remain after the reaction is complete. Use this understanding to calculate the concentrations of ions in the solution.
