А) Fe(OH)₂↓+2HNO₃= Fe(NO₃)₂+2H₂O
Fe(OH)₂↓ + 2H⁺ + 2NO₃⁻ = Fe²⁺ + 2NO₃⁻ + 2H₂O
  Fe(OH)₂↓ + 2H⁺ = Fe²⁺ + 2H₂O

б) 2Fe(OH)₃↓+3H₂SO₄=Fe₂(SO₄)₃+6H₂O
2Fe(OH)₃↓ + 6H⁺ + 3SO₄²⁻ = 2Fe³⁺ + 3SO₄²⁻ + 6H₂O
Fe(OH)₃↓ + 3H⁺ = Fe³⁺ + 3H₂O

в) MgCO₃↓+2HCl=MgCl₂+H₂O+CO₂↑
MgCO₃↓ + 2H⁺ + 2Cl⁻ = Mg²⁺ + 2Cl⁻ + H₂O + CO₂↑
  MgCO₃↓ + 2H⁺ = Mg²⁺ + H₂O + CO₂↑

г) Cu(OH)₂↓ + 2HNO₃ = Cu(NO₃)₂ + 2H₂O
  Cu(OH)₂↓ + 2H⁺ + 2NO₃⁻ = Cu²⁺ + 2NO₃⁻ + 2H₂O
  Cu(OH)₂↓ + 2H⁺ = Cu²⁺ + 2H₂O

д) 2Al(OH)₃↓+3H₂SO₄ = Al₂(SO₄)₃ + 6H₂O
  2Al(OH)₃↓ + 6H⁺ + 3SO₄²⁻ = 2Al³⁺ + 3SO₄²⁻ + 6H₂O
  Al(OH)₃↓ + 3H⁺ = Al³⁺ + 3H₂O
