A 25.0 cm³ sample of 0.180 mol/dm³ sodium hydroxide is neutralised by sulfuric acid:
H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O.
What is the concentration of H₂SO₄ if 21.0 cm³ is required?
H₂SO₄ + 2NaOH → Na₂SO₄ + 2H₂O.
What is the concentration of H₂SO₄ if 21.0 cm³ is required?
- 0.107 mol/dm³
- 0.214 mol/dm³
- 0.086 mol/dm³
- 0.180 mol/dm³
