Объяснение:

1)

Al₂(SO₄)₃ + 6KOH = 2Al(OH)₃↓ + 3K₂SO₄

2Al³⁺ + 3SO₄²⁻ + 6K⁺ + 6OH⁻ = 2Al(OH)₃↓ + 6K⁺ + 3SO₄²⁻

Al³⁺ + 3OH⁻ = Al(OH)₃↓

2)

FeSO₄ + 2LiOH = Li₂SO₄ + Fe(OH)₂↓

Fe²⁺ + SO₄²⁻ + 2Li⁺ + 2OH⁻ = 2Li⁺ + SO₄²⁻ + Fe(OH)₂↓

Fe²⁺ + 2OH⁻ = Fe(OH)₂↓

3)

Fe(NO₃)₃ + 3NaOH = Fe(OH)₃↓ +3NaNO₃

Fe³⁺ + 3NO₃⁻ + 3Na⁺ + 3OH⁻ = Fe(OH)₃↓ + 3Na⁺ + 3NO₃⁻

Fe³⁺ + 3OH⁻ = Fe(OH)₃↓
