Dilution Calculator for Solutions | Find the Right Amount of Solvent
Calculate the concentration or volume needed when preparing a diluted solution. Use the standard dilution relationship to determine unknown values from the original solution and desired final mixture.
About Dilution Calculator
Preparing a diluted solution is a routine task in chemistry, but getting the proportions right matters. When a stock solution is mixed with additional solvent, the amount of dissolved solute stays the same while the total volume increases. The concentration therefore becomes lower.
A Dilution Calculator makes it easier to work out the required concentration or volume without repeatedly rearranging equations. For a simple dilution, the familiar relationship C₁V₁ = C₂V₂ connects the starting and final solution conditions.
This tool can be useful for students, laboratory technicians, teachers, and anyone preparing solutions for experiments. You can use it to determine how much stock solution is needed for a target concentration or check the concentration obtained after dilution.
One practical tip is to use compatible volume units on both sides of the equation. For example, if both volumes are entered in milliliters, there is no need to convert them to liters before applying the formula. Also remember that this basic equation assumes the solute itself is not lost or chemically changed during dilution.
