1. What is the Allegation Calculator?

The Allegation Calculator is used to determine the ratio in which two ingredients of different strengths must be mixed to obtain a desired intermediate strength. This is particularly useful in pharmaceutical calculations and mixture problems.

2. How Does the Calculator Work?

The calculator uses the allegation formula:

Where:

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

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

3. Importance of Allegation Calculation

Details: Accurate allegation calculations are crucial in pharmacy, chemistry, and manufacturing to ensure proper mixing of components to achieve specific concentrations or properties.

4. Using the Calculator

Tips: Enter the high value (stronger component), desired target value, and low value (weaker component). The desired value must be between the high and low values.

5. Frequently Asked Questions (FAQ)

Q1: What does the allegation ratio mean?
A: The ratio indicates how many parts of the weaker component should be mixed with one part of the stronger component.

Q2: Can this be used for liquid mixtures?
A: Yes, the allegation method works for both solid and liquid mixtures.

Q3: What if my desired value equals my high or low value?
A: Then you don't need to mix - just use the pure high or low component.

Q4: Why is the ratio unitless?
A: Because it represents a proportion between two quantities with the same units.

Q5: Can this calculator handle percentage concentrations?
A: Yes, as long as all values use the same units (e.g., all percentages or all mg/mL).
