Answer:
H₂O, Na⁺, and SO₄²⁻
Explanation:
NaOH and H₂SO₄ are strong electrolytes. They will ionize completely
.
Molecular equation: 2NaOH + H₂SO₄ ⟶ Na₂SO₄ + 2H₂O
Ionic equation: 2Na⁺ + 2OH⁻ + 2H⁺ + SO₄²⁻ ⟶ 2Na⁺ + SO₄²⁻+ 2H₂O
- The concentration of water is 55.5 mol·L⁻¹.
- The concentration of Na⁺ is twice that of SO₄²⁻ .
- Hydrolysis of SO₄²⁻ is negligible.
The principal components in the flask at the endpoint are H₂O, Na⁺, and SO₄²⁻.
