Alligation Method
Alligation Rule
Higher Conc - Desired Conc = Parts of Lower
Desired Conc - Lower Conc = Parts of Higher
- • Used in pharmaceutical compounding
- • Calculates mixing ratios
- • Ensures accurate concentrations
- • Prevents calculation errors
Applications
- • Drug compounding
- • Solution preparation
- • Concentration blending
- • Quality control
- • Laboratory work
- • Manufacturing
Alligation Example
Problem
Mix 50% and 10% solutions to make 25% solution
- • Higher concentration: 50%
- • Lower concentration: 10%
- • Desired concentration: 25%
Solution
- • Parts of 50%: 25 - 10 = 15
- • Parts of 10%: 50 - 25 = 25
- • Total parts: 15 + 25 = 40
- • Ratio: 15:25 or 3:5
