1.
The ionic equation is:
H⁺(aq) + NO₃⁻(aq) + Na⁺(aq) + OH⁻(aq) → Na⁺(aq) + NO₃⁻(aq) + H₂O(l)
HNO₃(aq) + NaOH(aq) → NaNO₃(aq) + H2O(l)
The required dissociations are
HNO₃(aq) → H⁺(aq) + NO₃⁻(aq)
NaOH(aq) → Na⁺(aq) + OH⁻(aq)
NaNO₃(aq) → Na⁺(aq) + NO₃⁻(aq)
So, the ionic equation is
H⁺(aq) + NO₃⁻(aq) + Na⁺(aq) + OH⁻(aq) → Na⁺(aq) + NO₃⁻(aq) + H₂O(l)
2.
The ionic equation is
H⁺(aq) + Cl⁻(aq) + K⁺(aq) + OH⁻(aq) → K⁺(aq) + Cl⁻(aq) + H₂O(l)
HCl(aq) + KOH(aq) → KCl(aq) + H2O(l)
The required dissociations are
HCl(aq) → H⁺(aq) + Cl⁻(aq)
KOH(aq) → K⁺(aq) + OH⁻(aq)
KCl(aq) → K⁺(aq) + Cl⁻(aq)
So, the ionic equation is
H⁺(aq) + Cl⁻(aq) + K⁺(aq) + OH⁻(aq) → K⁺(aq) + Cl⁻(aq) + H₂O(l)
3.
The ionic equation is
2H⁺(aq) + SO₄²⁻(aq) + Mg²⁺(aq) + 2OH⁻(aq) → Mg²⁺(aq) + SO₄²⁻(aq)
+ 2H₂O(l)
H₂SO₄(aq) + Mg(OH)₂(aq) → MgSO₄(aq) + 2H2O(l)
The required dissociations are
H₂SO₄(aq) → 2H⁺(aq) + SO₄²⁻(aq)
Mg(OH)₂(aq) → Mg²⁺(aq) + 2OH⁻(aq)
MgSO₄(aq) → Mg²⁺(aq) + SO₄²⁻(aq)
So, the ionic equation is
2H⁺(aq) + SO₄²⁻(aq) + Mg²⁺(aq) + 2OH⁻(aq) → Mg²⁺(aq) + SO₄²⁻(aq)
+ 2H₂O(l)
