A stock solution refers to a concentrated solution that is prepared ahead of time and can be diluted to obtain solutions of desired concentrations for specific purposes. Stock solutions are often used to simplify preparation processes and ensure accuracy.
The amount of solute present per unit volume or mass of solvent or solution.
Dilution factor: The ratio between the final volume (diluted solution) and initial volume (stock solution) when preparing a diluted solution from a stock solution.
Serial dilution: A stepwise dilution process where each subsequent dilution is based on the previous one, resulting in progressively lower concentrations.
