A student titrates 25.0 cm³ of aqueous sodium hydroxide with 0.150 mol/dm³ sulfuric acid. The neutralisation reaction is:
H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + 2H₂O(l).
If 20.0 cm³ of the acid is required to reach the end‑point, what is the concentration of the sodium hydroxide solution?
H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + 2H₂O(l).
If 20.0 cm³ of the acid is required to reach the end‑point, what is the concentration of the sodium hydroxide solution?
- 0.120 mol/dm³
- 0.180 mol/dm³
- 0.240 mol/dm³
- 0.360 mol/dm³
