What is CaCl₂?
Two aqueous ionic compounds exchange ions and form an insoluble solid.
What is a double replacement (precipitation) reaction?
Balance: Na₃PO₄ + MgCl₂ → Mg₃(PO₄)₂ + NaCl
What is 2,3,1,6?
Predict products: Ba(OH)₂ + H₂SO₄ →

Write the formula for iron(III) oxide.
What is Fe₂O₃?
Classify: 2KClO₃ → 2KCl + 3O₂
What is a decomposition reaction?
Balance: Fe₂(SO₄)₃ + KOH → Fe(OH)₃ + K₂SO₄
What is 1,6,2,3?

What is synthesis?
Balance: (NH₄)₂Cr₂O₇ → Cr₂O₃ + N₂ + H₂O
What is 1,1,1,4?
Predict products and state if a precipitate forms:
Pb(NO₃)₂ + Na₂S →
What is PbS(s) + 2NaNO₃(aq)?
Why must solubility rules be applied to products, not reactants?
Because precipitates depend on the solubility of the products formed.
Write the formula for copper(II) hydroxide.
What is Cu(OH)₂?
