Alligation Medial
Alligation Medial is quite calculated differently than your usual alternate Alligation (tic tac toe) Method! I decided to review the Alligation Medial Method because many techs tend to get confuse by it because of the name similarity.
Define: The Alligation Medial is used to calculate to figure out the total % strength when two or more liquid solutions are mixed.
Define: The Alligation (tic tac toe) Method is used to calculate when two solution strengths (%) is mixed into the desired strength (prescribed by dr.) to get a specific amount of milliliter for each two solution strengths (%) as explained above to equal our final liquid (ml) volume that was prescribed as given.
Ex 1) What is the percentage of alcohol in the following mixture?
Alcohol 2% 5 ml
Alcohol 4% 10 ml
Step 1: Add the quantity of all milliliter components
5 ml + 10 ml = 15 ml
Step 2: Multiply the quantity of each milliliter component used in the mixture by it's corresponding % strength, and then add up the products
* 5 ml x 2% = 10
* 10 ml x 4% = 40
* 10 + 40 = 50
Step 3: Divide the final value from step 2 by the final value in step 1
50 / 15 ml = 3.33% answer
What is the percentage of alcohol in the following mixture?
Tincture A- 110 ml 35% alcohol
Tincture B- 220 ml 25% alcohol
Tincture C- 330 ml 20% alcohol
Answer: 24.17%
