Expert Solution

Introduction

The process of reducing a solute concentration by adding solvent to a solution is referred to as dilution.

The stock solution is an initial solution (high concentration) in which diluent is added to make a final solution with the required concentration (low concentration).

A factor that dilutes the stock solution to the desired concentration is the dilution factor (DF). DF is expressed by the ratio of the final volume (diluted solution) to the initial volume (undiluted solution).
