Question

Which of the following combinations will result in a precipitate, according to

solubility rules?

Sodium nitrate (Na2CrO4) and barium chloride (BaCl2)
Calcium sulfate (CaSO4) and sodium carbonate (Na2CO3)
Ammonium chloride (NH4CI) and sodium hydroxide (NaOH)
Potassium iodide (KI) and silver nitrate (AgNO3)

Answer 1

Potassium iodide (KI) and silver nitrate (AgNO3)

Step-by-step explanation:

Answer 2

Step-by-step explanation:

The combination that will result in a precipitate, according to solubility rules, is:

Potassium iodide (KI) and silver nitrate (AgNO3)

This is because silver iodide (AgI) is insoluble in water and will precipitate out of the solution. The other combinations do not result in a precipitate because all the products are soluble in water according to solubility rules.
