Dilution is the process of reducing the concentration of a solution by adding more solvent. It is commonly used in laboratories to prepare solutions with specific concentrations.
What is dilution?
Dilution decreases solution concentration while keeping the amount of solute constant. The total solution volume increases when additional solvent is added.
Dilution formula and calculation
The dilution formula C1V1 = C2V2 relates the initial concentration and volume to the final concentration and volume. It helps determine how much concentrated solution is required to prepare a diluted solution.
How dilution is used in laboratories
Scientists use dilution calculations when preparing standard solutions, chemical samples, and experimental mixtures with precise concentrations.
Common dilution mistakes
Common mistakes include mixing up initial and final concentrations, using incorrect volume units, and forgetting that the amount of solute remains unchanged during dilution.
Frequently Asked Questions
What is the dilution formula?
The dilution formula is C1V1 = C2V2, where initial concentration multiplied by initial volume equals final concentration multiplied by final volume.
What happens to concentration during dilution?
Adding solvent increases the total volume and decreases the concentration of the solution.
