1. What is the Alligation Method?

The alligation method is a mathematical technique 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 scientific fields.

2. How Does the Calculator Work?

The calculator uses the alligation method formula:

\[ \text{Ratio} = \frac{\text{High Concentration} - \text{Desired Concentration}}{\text{Desired Concentration} - \text{Low Concentration}} \]

Where:

Explanation: The result shows how many parts of the lower concentration solution should be mixed with 1 part of the higher concentration solution to achieve the desired concentration.

3. Importance of Alligation Method

Details: The alligation method is crucial for preparing solutions of specific concentrations in laboratories, pharmaceutical preparations, and industrial applications where precise mixtures are required.

4. Using the Calculator

Tips: Enter all concentrations in percentage (%). The desired concentration must be between the high and low concentrations. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

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

Q2: Can I use different units besides percentage?
A: Yes, as long as all three values use the same units (mg/mL, g/L, etc.), the ratio will be correct.

Q3: What if my desired concentration is outside the range?
A: The calculator won't provide a valid result as you cannot achieve a concentration outside the range of your two stock solutions.

Q4: How precise is this method?
A: The method is mathematically precise, but actual results may vary slightly due to measurement errors and solution properties.

Q5: Can this be used for more than two solutions?
A: The basic alligation method is for two solutions. More complex methods exist for multiple solutions.
