Question

Which of the following pairs of aqueous solutions, when mixed, would result in the formation of a precipitate?
Options
A KNO₃ and ZnSO₄
B NH₄Cl and NaOH
C Na₂SO₄ and Ba(NO₃)₂
Correct Answer
D CuSO₄ and LiCl
Correct Answer

Option C is the correct answer.

Detailed Explanation

Na₂SO₄ and Ba(NO₃)₂ react to form BaSO₄, which is insoluble in water and precipitates. The other combinations do not produce an insoluble product (or produce a soluble one).

Hint

Check solubility rules: sulfates are generally soluble except with Ba²⁺, Pb²⁺, Ca²⁺, etc.
