In an experiment, 25.0 cm³ of sodium hydroxide solution is completely neutralised by 0.200 mol/dm³ hydrochloric acid according to the equation:
NaOH + HCl → NaCl + H₂O
What is the concentration of the sodium hydroxide solution if 20.0 cm³ of the acid is required for complete neutralisation?
NaOH + HCl → NaCl + H₂O
What is the concentration of the sodium hydroxide solution if 20.0 cm³ of the acid is required for complete neutralisation?
- 0.125 mol/dm³
- 0.160 mol/dm³
- 0.200 mol/dm³
- 0.250 mol/dm³
