A 25.0 cm³ sample of sodium carbonate solution is titrated with 0.100 mol/dm³ hydrochloric acid. The equation is
Na₂CO₃ + 2HCl → 2NaCl + H₂O + CO₂.
If 30.0 cm³ of the acid is needed to reach the end‑point, what is the concentration of the sodium carbonate solution?
Na₂CO₃ + 2HCl → 2NaCl + H₂O + CO₂.
If 30.0 cm³ of the acid is needed to reach the end‑point, what is the concentration of the sodium carbonate solution?
- 0.0600 mol/dm³
- 0.0300 mol/dm³
- 0.0120 mol/dm³
- 0.120 mol/dm³
