The vapor pressure of a pure solvent is influenced by its concentration, but changing the concentration of a pure solvent without adding a solute is not feasible in a typical context. Concentration changes usually involve the addition or removal of solutes. When discussing vapor pressure, it's important to note that it is primarily affected by temperature and the nature of the solvent itself. As the concentration of a pure solvent increases (for instance, by reducing the volume of the system while keeping the amount of solvent constant), the vapor pressure can be affected due to changes in the physical properties of the solvent. However, in practical terms, altering the concentration of a pure solvent without a solute is not a common scenario, making it a theoretical discussion rather than one grounded in typical laboratory practices.
