1. What is the Dilution Formula?

The dilution formula calculates the new concentration of a solution after dilution. It's based on the principle that the amount of solute remains constant while the volume changes.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

• Initial Concentration — Original concentration of the solution (mg/L)
• V1 — Initial volume of the solution (L)
• V2 — Final volume after dilution (L)

Explanation: The formula shows that concentration decreases proportionally as volume increases.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in chemistry, biology, medicine, and environmental science for preparing solutions of desired concentrations.

4. Using the Calculator

Tips: Enter initial concentration in mg/L, initial volume (V1) in liters, and final volume (V2) in liters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What if my volumes are in milliliters?
A: Convert to liters first (1 L = 1000 mL) or modify the formula to use consistent units throughout.

Q2: Can this calculator be used for serial dilutions?
A: This calculates single-step dilutions. For serial dilutions, you would need to perform multiple calculations.

Q3: What's the difference between dilution factor and dilution ratio?
A: Dilution factor is V2/V1, while dilution ratio is typically expressed as 1:V2/V1.

Q4: Does temperature affect dilution calculations?
A: Temperature affects solution volume slightly, but for most practical purposes, this effect is negligible in dilution calculations.

Q5: How precise should my measurements be?
A: Precision depends on your application. Analytical chemistry often requires high precision (4+ decimal places), while general purposes may need less.
