Alligation / Mixture Calculator
Standard pharmaceutical calculation, laboratory analysis and research tools.
Solve pharmaceutical mixture and alligation problems involving different strengths, proportions and target concentrations using standard alligation concepts.
What Is Alligation?
Alligation is a traditional pharmaceutical calculation method used to determine the proportions in which substances of different strengths should be mixed to obtain a desired final strength.
Alligation Alternate
Alligation alternate uses the differences between the desired strength and the strengths of the available components to establish their relative mixing proportions.
Alligation Medial
Alligation medial is used to determine the resulting average strength of a mixture when the quantities and strengths of the components are known.
How to Solve Mixture Problems
Identify the high-strength and low-strength components, establish the desired concentration and calculate the required relative quantities. The final result should be checked against the target strength.
Pharmaceutical Applications
Alligation calculations are useful in pharmaceutical compounding, formulation exercises, concentration adjustment and pharmacy examination problems involving mixtures of different strengths.
Frequently Asked Questions
What is alligation alternate used for?
It is used to determine the relative proportions of components of different strengths required to obtain a desired strength.
What is alligation medial?
It is used to calculate the average or resulting strength of a mixture from known component quantities and strengths.
Can alligation be used for any mixture?
It is appropriate for problems where the component strengths and target or resulting strength are expressed on a compatible basis.
