Question 12

In a titration, 30.0 cm3 of 0.0800 mol/dm3 potassium hydroxide solution is exactly neutralised by 20.0 cm3 of nitric acid. The equation is KOH+HNO3→KNO3+H2O\text{KOH} + \text{HNO}_3 \rightarrow \text{KNO}_3 + \text{H}_2\text{O}KOH+HNO3​→KNO3​+H2​O. What is the concentration of the nitric acid?
