**Question:**

Which of the following solutions, when mixed, will result in a precipitate?

**Select one:**

- a. NaCl + FeSO₄
- b. NaCl + KI
- c. NaCl + MnI₂
- d. NaCl + CuSO₄
- e. NaCl + Pb(NO₃)₂

**Explanation:**

To answer this question, you need to know about the solubility rules in chemistry. Precipitation occurs when a product of a reaction between two solutions is insoluble in water, forming a solid (precipitate). Commonly, lead chloride (PbCl₂) is one such insoluble salt that forms a precipitate.

**Correct Answer:**

Option e: NaCl + Pb(NO₃)₂

Mixing NaCl and Pb(NO₃)₂ results in the formation of PbCl₂, which precipitates out of the solution.
