Question

Составьте уравнения РИО
AgF+Na3PO4
Al2(SO4)3+K2S

Answer 1

3AgF + Na₃PO₄ = Ag₃PO₄ + 3NaF

3Ag⁺ + 3F⁻ + 3Na⁺ + PO₄³⁻ = Ag₃PO₄ + 3Na⁺ + 3F⁻

3Ag⁺ + PO₄³⁻ = Ag₃PO₄


Al₂(SO₄)₃ + 3K₂S + 6H₂O = 2Al(OH)₃↓ + 3H₂S↑ + 3K₂SO₄

2Al³⁺ + 3SO₄²⁻ + 6K⁺ + 3S²⁻ + 6H₂O = 2Al(OH)₃ + 3H₂S + 6K⁺ + 3SO₄²⁻

2Al³⁺ + 3S²⁻ + 6H₂O = 2Al(OH)₃ + 3H₂S
