What is this calculator for?

The Alligation Calculator helps determine the correct ratio or volume of two solutions with different concentrations to mix a final solution with a desired concentration.

How to use this calculator?

1. Enter the concentrations of the two solutions and the desired final concentration.
2. Optionally, enter volumes to see if they match the calculated ratios.
3. Click "Calculate" to get the required mixing ratio or validation.

Formula Used:

Parts of C1 : Parts of C2 = (C2 - Cm) : (Cm - C1)

Example:

If you want to prepare a 30% solution using a 20% and a 50% solution:

Ratio = (50 - 30) : (30 - 20) = 20 : 10 = 2 : 1

This means mix 2 parts of the 20% solution with 1 part of the 50% solution.
