1. What is Alligation?

Alligation is a mathematical method used to calculate the proportion of different concentrations needed to achieve a desired intermediate concentration. It's commonly used in pharmacy, chemistry, and manufacturing.

2. How Does the Calculator Work?

The calculator uses the alligation formula:

Where:

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

Explanation: The formula calculates the ratio in which two different concentration solutions must be mixed to obtain a desired intermediate concentration.

3. Importance of Alligation

Details: Alligation is crucial for preparing specific concentrations in pharmaceutical compounding, chemical solutions, and industrial applications where precise mixtures are required.

4. Using the Calculator

Tips: Enter the high and low concentrations along with your desired concentration. All values must be positive numbers with the high concentration greater than the low concentration.

5. Frequently Asked Questions (FAQ)

Q1: What if my desired concentration is outside the range?
A: The desired concentration must be between the high and low concentrations for the alligation method to work.

Q2: Can I use this for solid mixtures?
A: Yes, alligation can be used for both liquid solutions and solid mixtures as long as the units are consistent.

Q3: How precise is this method?
A: Alligation provides mathematically precise ratios, but actual results depend on accurate measurement when mixing.

Q4: What if I get a negative result?
A: Negative results typically mean your desired concentration is outside the range of your high and low concentrations.

Q5: Can I use different units?
A: Yes, as long as all concentrations use the same units (%, mg/mL, etc.), the ratio will be correct.
