a) BaCl₂ + Na₂SO₄ → BaSO₄ + 2NaCl
Ba²⁺ + 2Cl⁻ + 2Cl⁻ + 2Na⁺ + SO₄²⁻ → BaSO₄ + 2Na⁺ + 2Cl⁻
Ba²⁺ + SO₄²⁻ → BaSO₄ -osad
b) AgNO₃ + NaCl → AgCl + NaNO₃
Ag₊ + NO₃⁻ + Na⁺ + Cl⁻ → AgCl + Na⁺ + NO₃⁻
Ag₊ + Cl⁻ → AgCl -osad

a) AlCl₃ + 3NaOH → Al(OH)₃ + 3NaCl
Al³⁺ + 3Cl⁻ + 3Na⁺ + 3OH⁻ → Al(OH)₃ + 3Na⁺ + 3Cl⁻
Al³⁺+ 3OH⁻ → Al(OH)₃ osad
b)CuSO₄ + 2KOH →Cu(OH)₂ + K₂SO₄
Cu²⁺ + SO₄²⁻ + 2K⁺ + 2OH⁻ → Cu(OH)₂ + 2K⁺ + SO₄²
Cu²⁺ + 2OH⁻ → Cu(OH)₂ osad
