A numerical expression indicating the extent to which a solution has been weakened by the addition of a solvent. It represents the ratio of the initial volume to the final volume, providing a standardized method for quantifying solution concentration changes. For instance, adding one part of a concentrated stock solution to nine parts of a diluent results in a tenfold, or 1:10, reduction in concentration. This numerical value facilitates calculations in various scientific disciplines.
The described value is fundamentally important in scientific experimentation and industrial processes requiring precise control over concentration. Accurate determination of this value ensures reproducibility and allows for predictable results. Its consistent use has standardized protocols across fields such as chemistry, biology, and pharmaceuticals, contributing to the reliability and comparability of experimental data. Historically, this methodology has been crucial in titrations, serial dilutions for cell culture, and creating accurate standard curves for analytical instruments.
