1)
Cu(NH₃)₄CO₃ → Cu(NH₃)₄²⁺ + CO₃²⁻
2 ions are formed.
2)
KAl(SO₄)₂ → K⁺ + Al³⁺ + 2SO₄²⁻
4 ions are formed.
3)
Ba(OH)₂ → Ba²⁺ + 2OH⁻
3 ions are formed.
4)
H₂SO₄ → H⁺ + HSO₄⁻
HSO₄⁻ ⇌ H⁺ + SO₄²⁻
Less than 3 ions are formed.
5)
FeCl₂ → Fe²⁺ + 2Cl⁻
3 ions are formed.
The answer is : 2) KAl(SO₄)₂
Cu(NH₃)₄CO₃ → Cu(NH₃)₄²⁺ + CO₃²⁻
2 ions are formed.
2)
KAl(SO₄)₂ → K⁺ + Al³⁺ + 2SO₄²⁻
4 ions are formed.
3)
Ba(OH)₂ → Ba²⁺ + 2OH⁻
3 ions are formed.
4)
H₂SO₄ → H⁺ + HSO₄⁻
HSO₄⁻ ⇌ H⁺ + SO₄²⁻
Less than 3 ions are formed.
5)
FeCl₂ → Fe²⁺ + 2Cl⁻
3 ions are formed.
The answer is : 2) KAl(SO₄)₂
