A student titrates 25.0 cm³ of hydrochloric acid with 0.200 mol/dm³ sodium hydroxide. The equation is
HCl + NaOH → NaCl + H₂O.
If 18.5 cm³ of NaOH is needed to reach the end‑point, what is the concentration of the HCl solution?
HCl + NaOH → NaCl + H₂O.
If 18.5 cm³ of NaOH is needed to reach the end‑point, what is the concentration of the HCl solution?
- 0.148 mol/dm³
- 0.0740 mol/dm³
- 0.270 mol/dm³
- 0.540 mol/dm³
