Question

Запишите краткое и ионное реакции:
KOH+H3PO4=
AgNO3+FeCl2=
ZnSO4+KOH=

Answer 1

1:
3KOH+H₃PO₄=K₃PO₄+3H₂O
3K⁺ + 3OH⁻ + 3H⁺ + PO₄³⁻ = 3K⁺ + PO₄³⁻ + 3H₂O
3H⁺ + 3OH⁻ = 3H₂O
2:
2AgNO₃+FeCl₂=2AgCl↓+Fe(NO₃)₂
2Ag⁺ + 2NO₃⁻ + Fe²⁺ + 2Cl⁻ = 2AgCl↓ + Fe²⁺ + 2NO₃⁻
2Ag⁺ + 2Cl⁻ = 2AgCl↓
3:
ZnSO₄+2KOH=Zn(OH)₂↓+K₂SO₄|
Zn²⁺ + SO₄²⁻ + 2K⁺ + 2OH⁻ = Zn(OH)₂↓ + 2K⁺ +SO₄²⁻
Zn²⁺ + 2OH⁻ = Zn(OH)₂↓
