When it comes to mixing two substances with different concentrations, the alligation method is a valuable tool in chemistry, medicine, and various industries. The concept behind alligation is to combine two substances in such a way that the resulting mixture reaches a desired concentration. Whether you’re working with medications, chemical solutions, or even in laboratory settings, this technique helps achieve a specific concentration by combining substances of different strengths.
In this article, we’ll explore the Alligation Calculator, a tool that simplifies the process of calculating the concentration and volume of a mixed solution. We’ll discuss how it works, provide step-by-step instructions on how to use it, and offer real-life examples. Additionally, we’ll answer common questions related to the alligation method to enhance your understanding.
What is Alligation?
Alligation is a mathematical process used to mix two or more substances of different concentrations to obtain a mixture with a desired concentration. This technique is frequently used in fields like pharmacy, medicine, and chemistry. In simpler terms, alligation helps determine the proper quantities of two substances with different concentrations to create a specific concentration.
Understanding the Alligation Formula
The formula for calculating the result of mixing two solutions with different concentrations is as follows:
- Concentration Result (C):
C = ((C1 × V1) + (C2 × V2)) / (V1 + V2)
Where:
- C1 = Concentration of the first solution
- V1 = Volume of the first solution
- C2 = Concentration of the second solution
- V2 = Volume of the second solution
- C = Concentration of the final mixture
- Total Volume (V):
V = V1 + V2
This formula allows us to determine both the concentration and the volume of the final mixture.
How to Use the Alligation Calculator
The Alligation Calculator tool simplifies this process by automating the calculations. Below are the steps on how to use the calculator:
- Enter the Concentration and Volume of the First Solution:
You will be asked to input the concentration and volume for the first substance (C1 and V1). The concentration is typically expressed as a percentage (%), and the volume is entered in milliliters (ml). - Enter the Concentration and Volume of the Second Solution:
Next, input the concentration and volume for the second substance (C2 and V2), just as you did for the first solution. - Click “Calculate”:
After entering the necessary values, click the “Calculate” button to get the results. - View the Results:
The calculator will then show you two important results:- Concentration of the Resulting Mixture (C): This is the concentration of the final solution after mixing.
- Total Volume of the Resulting Mixture (V): This is the combined volume of both solutions.
Example of Using the Alligation Calculator
Let’s go through an example to better understand how the alligation method works.
Example 1: Mixing Two Concentrations
- Solution 1: Concentration = 30%, Volume = 50 ml
- Solution 2: Concentration = 10%, Volume = 150 ml
Step 1: Input the values into the Alligation Calculator:
- C1 = 30%, V1 = 50 ml
- C2 = 10%, V2 = 150 ml
Step 2: Click Calculate.
Step 3: The calculator will compute the concentration and total volume of the mixture:
- Concentration Result (C) = ((30 × 50) + (10 × 150)) / (50 + 150)
C = (1500 + 1500) / 200
C = 3000 / 200
C = 15% - Total Volume (V) = 50 + 150 = 200 ml
Thus, after mixing the two solutions, the resulting concentration is 15%, and the total volume is 200 ml.
