A student titrates 25.0 cm³ of sodium hydroxide solution with 0.200 mol dm⁻³ sulfuric acid, H₂SO₄. The neutralisation equation is:
H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + 2H₂O(l)
If 15.0 cm³ of the acid is needed for complete neutralisation, what is the concentration of the NaOH solution?
H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + 2H₂O(l)
If 15.0 cm³ of the acid is needed for complete neutralisation, what is the concentration of the NaOH solution?
- 0.240 mol dm⁻³
- 0.120 mol dm⁻³
- 0.360 mol dm⁻³
- 0.480 mol dm⁻³
