Understanding the Dilution Principle
Dilution represents the process of decreasing the concentration of a solute in a solution by adding more solvent. This fundamental laboratory operation follows the principle of mass conservation, where the amount of solute remains constant while the total volume increases. Understanding this principle is essential for proper utilization of this science calculator.
The relationship between initial and final concentrations follows the mathematical equation C1V1 = C2V2, where C represents concentration and V represents volume. This equation forms the foundation of all dilution calculations and represents the core calculation that this tool addresses for scientific solution preparation.
The Dilution Equation: C1V1 = C2V2
The dilution equation C1V1 = C2V2 mathematically represents the conservation of mass principle in solution preparation. In this equation, C1 represents the initial (stock) concentration, V1 represents the initial volume used, C2 represents the final (desired) concentration, and V2 represents the final total volume. This equation allows calculation of any one variable when the other three are known.
The equation's importance lies in its universal application across all scientific disciplines involving solution preparation. Understanding and properly applying this equation using this online calculator ensures accurate solution preparation for experiments, assays, standards, and working solutions in research and laboratory settings.
