1. What is the Alligation Formula?

The alligation formula is a mathematical method used to calculate the ratio in which two solutions of different concentrations must be mixed to obtain a desired intermediate concentration. It's commonly used in pharmacy, chemistry, and various mixing applications.

2. How Does the Calculator Work?

The calculator uses the alligation formula:

Where:

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

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

3. Importance of Alligation Calculation

Details: Alligation is crucial for accurately preparing solutions of specific concentrations, especially in pharmaceutical preparations, chemical dilutions, and various industrial mixing applications.

4. Using the Calculator

Tips: Enter all concentrations in the same units. The high concentration must be greater than the desired concentration, which must be greater than the low concentration.

5. Frequently Asked Questions (FAQ)

Q1: What if my desired concentration equals my low concentration?
A: The denominator becomes zero, making the ratio undefined. This means you should use only the low concentration solution.

Q2: Can I use this for more than two components?
A: This calculator handles two-component mixtures. For more components, you would need to perform multiple alligation calculations.

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

Q4: How do I interpret the ratio?
A: The ratio tells you how many parts of the higher concentration solution to mix with 1 part of the lower concentration solution.

Q5: What if my desired concentration is outside the range?
A: The desired concentration must be between the high and low concentrations for the formula to work.
