Question

в молекулярной и ионной формах al2(so4)3+na3po4 и pbohno3+naoh

Answer 1

Al₂(SO₄)₃ + 2Na₃PO₄  = 3Na₂SO₄ + 2AlPO₄↓
2Al³⁺ + 3SO₄²⁻ + 6Na⁺ + 2PO₄⁻  = 6Na⁺ + 3SO₄²⁻ + 2AlPO₄↓
2Al³⁺ + 2PO₄⁻  = 2AlPO₄↓

(PbOH)NO₃ + NaOH = Pb(OH)₂↓ + NaNO₃
(PbOH)⁺ + NO₃⁻ + Na⁺ + OH⁻ = Pb(OH)₂↓ + Na⁺ + NO₃⁻
(PbOH)⁺ + OH⁻ = Pb(OH)₂↓
