Water Dilution Calculator

Formula

To calculate the amount of water needed (W):

$W = \frac{C1 \times V1 - C2 \times V2}{C2}$

Where:

$W$ is the Amount of Water to Add (ml)
$C1$ is the Initial Concentration of the Solution (mg/ml)
$V1$ is the Initial Volume of the Solution (ml)
$C2$ is the Desired Final Concentration (mg/ml)
$V2$ is the Desired Final Volume of the Solution (ml)

What is Water Dilution?

Water dilution refers to the process of reducing the concentration of a substance in a solution or mixture by adding more water. This method is commonly used in various fields such as chemistry, cooking, and pharmaceuticals to adjust the strength or potency of a substance. The end result is a less concentrated, or diluted, solution that maintains the original substance's properties but at a lower intensity.

Example Calculation

Let's assume the following values:

Initial Concentration ( $C1$ ) = 10 mg/ml
Initial Volume ( $V1$ ) = 100 ml
Desired Final Concentration ( $C2$ ) = 5 mg/ml
Desired Final Volume ( $V2$ ) = 200 ml

Using the formula:

$W = \frac{10 \times 100 - 5 \times 200}{5} = \frac{1000 - 1000}{5} = 0 \text{ ml}$

The Amount of Water Needed is 0 ml.
