1. What is the Allegation Formula?

The Allegation Formula (also called Alligation Method) is used to calculate the ratio in which two different concentrations must be mixed to obtain a desired intermediate concentration.

2. How Does the Calculator Work?

The calculator uses the Allegation formula:

Where:

• \( High \) — Higher concentration component
• \( Desired \) — Target concentration
• \( Low \) — Lower concentration component

Explanation: The formula calculates the parts of the higher concentration solution needed per part of the lower concentration solution to achieve the desired concentration.

3. Importance of Mixing Ratio

Details: This calculation is crucial in pharmacy, chemistry, and manufacturing where precise mixing of different concentrations is required to achieve a specific target concentration.

4. Using the Calculator

Tips: Enter all concentrations in the same units. The desired concentration must be between the high and low values. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What if my desired concentration equals one of the inputs?
A: If desired equals high, you only need the high concentration solution. If it equals low, you only need the low concentration solution.

Q2: Can I use this for more than two components?
A: The basic formula is for two components. For more complex mixtures, you would need to perform multiple calculations.

Q3: What units should I use?
A: Any consistent units can be used (%, mg/mL, etc.) as long as all inputs use the same units.

Q4: How precise is this method?
A: The method is mathematically exact for ideal solutions where concentrations mix linearly.

Q5: Can this be used for solid mixtures?
A: Yes, it can be used for solid mixtures by weight as long as the concentrations are properly defined.
