**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%**
