Ответ:
Объяснение:
а) 6KOH + Fe₂(SO₄)₃ = 2Fe(OH)₃ + 3K₂SO₄
6K⁺ + 6OH⁻ + 2Fe³⁺ + 3SO₄²⁻ = 2Fe(OH)₃ + 6K⁺ + 3SO₄²⁻
Fe³⁺ + 3OH⁻ = Fe(OH)₃
б) 2KOH + CO₂ = K₂CO₃ + H₂O
2K⁺ + 2OH⁻ + CO₂ = 2K⁺ + CO₃²⁻ + H₂O
2OH⁻ + CO₂ = CO₃²⁻ + H₂O
в) KOH + HNO3 = KNO₃ + H₂O
K⁺ + OH⁻ + H⁺ + NO₃⁻ = K⁺ + NO₃⁻ + H₂O
H⁺ + OH⁻ = H₂O
