Question

aqueous solutions of potassium sulfate and ammonium nitrate are mixed together. which statement is correct? a kno₃ will precipitate from solution. b a gas is released. c both kno₃ and nh₄so₄ precipitate from solution. d nh₄so₄ will precipitate from solution. e no reaction will occur.

Explanation:

Potassium sulfate ($K_2SO_4$) and ammonium nitrate ($NH_4NO_3$) are both soluble salts. When mixed, the possible products from double - displacement reaction are potassium nitrate ($KNO_3$) and ammonium sulfate ($(NH_4)_2SO_4$). According to solubility rules, all nitrates are soluble and most sulfates are soluble including ammonium sulfate. So no precipitate, gas formation or other chemical change occurs.

Answer:

E. No reaction will occur.
