DOL IP: Solubility and Precipitation Reactions

A student mixes Na₂S(aq) and FeCl₂(aq). Using solubility rules, what is the solid product formed, if any?

• FeS
• Na₂Fe
• FeS₂
• NaCl

When solutions of AgNO₃(aq) and K₂SO₄(aq) are mixed, which product forms a precipitate?

• Ag₂SO₄
• K₂S
• Ag₂SO₃

• AgCl

Use your solubility rules to determine which product is insoluble.

• NaCl

• Cu(OH)₂

• both

• neither

Predict the product of NaOH (aq) + CuCl₂ (aq) →

• NaCl (aq) + Cu(OH)₂ (s)

• NaCl (s) + Cu(OH)₂ (s)

• NaCl (s) + Cu(OH)₂ (aq)

• NaCl (aq) + Cu(OH)₂ (aq)
