Figure 1 shows the volumes of:

  • potassium hydroxide solution of concentration 0.20 mol/dm30.20\text{ mol/dm}^30.20 mol/dm3
  • nitric acid of concentration 0.05 mol/dm30.05\text{ mol/dm}^30.05 mol/dm3

which completely react to produce different masses of potassium nitrate.

Figure 1: Reactant volumes against mass of potassium nitrate produced

Determine the simplest whole number ratio of the volumes of:

potassium hydroxide solution:nitric acid\text{potassium hydroxide solution} : \text{nitric acid}potassium hydroxide solution:nitric acid

which completely react with each other. Use Figure 1.
