**Problem Statement: Precipitation Reaction Analysis**

*Scenario:*

When 18.0 mL of a 1.38 × 10⁻⁴ M calcium bromide solution is combined with 22.0 mL of a 2.10 × 10⁻⁴ M sodium phosphate solution, does a precipitate form? 

▢ (yes or no)

*Calculation Requirement:*

For these conditions, the Reaction Quotient, Q, is equal to: ▢ 

**Instructions:**

1. Determine if a precipitate forms by comparing the Reaction Quotient (Q) to the solubility product constant (Ksp) of the potential precipitate.
   
2. Calculate the concentration of ions when the solutions are mixed.

3. Use the ion concentrations to calculate Q.

4. Enter your results for Q and determine if precipitation occurs (yes or no).

**Note:** To solve this problem, ensure understanding of concepts like molarity, reaction quotients, and solubility product constants.
