Question

question 17 (5 points) which of the following reactions will not result in the formation of a precipitate? a) aqueous silver nitrate added to a solution containing potassium chloride b) aqueous solution of barium chloride added to a solution containing sodium sulfate c) aqueous solution of strontium chloride added to a solution containing potassium carbonate d) aqueous solution of sodium sulfate added to a solution containing ammonium iodide

Explanation:

• Option a: $\ce{AgNO3 + KCl -> AgCl(s) + KNO3}$, $\ce{AgCl}$ is a precipitate.
• Option b: $\ce{BaCl2 + Na2SO4 -> BaSO4(s) + 2NaCl}$, $\ce{BaSO4}$ is a precipitate.
• Option c: $\ce{SrCl2 + K2CO3 -> SrCO3(s) + 2KCl}$, $\ce{SrCO3}$ is a precipitate.
• Option d: $\ce{Na2SO4 + 2NH4I -> 2NaI + (NH4)2SO4}$, both products are soluble.

Answer:

d) aqueous solution of sodium sulfate added to a solution containing ammonium iodide
