Объяснение:
H2SO4 + PbCl2 = PbSO4 + 2HCl↑
2H⁺ + SO₄²⁻ + Pb²⁺ + 2Cl⁻ = Pb²⁺ + SO₄²⁻ + 2HCl↑
H⁺ + Cl⁻ = HCl↑
H2SO4 + Cu(OH)2 = CuSO4 + 2H2O
2H⁺ + SO₄²⁻ + Cu(OH)₂ = Cu²⁺ + SO4²⁻ + 2H₂O
2H⁺ + Cu(OH)₂ = Cu²⁺ + 2H₂O
H2SO4 + K2S = K2SO4 + H2S↑
2H⁺ + SO₄²⁻ + 2K⁺ + S²⁻ = 2K⁺ + SO₄²⁻ + H2S↑
2H⁺ + S²⁻ = H2S↑
3H2SO4 + 2Fe(OH)3 = Fe2(SO4)3 + 6H2O
6H⁺ + 3SO₄²⁻ + 2Fe(OH)₃ = 2Fe³⁺ + 3SO₄²⁻ + 6H₂O
6H⁺ + 2Fe(OH)₃ = 2Fe³⁺ + 6H₂O
