1. What is Dilution Factor?

The dilution factor (DF) is a ratio that describes how much a solution has been diluted. It represents the factor by which the original solution has been multiplied to achieve the final concentration.

2. How Does the Calculator Work?

The calculator uses the dilution factor formula:

Where:

• \( DF \) — Dilution factor (unitless)
• \( V1 \) — Initial volume of undiluted solution (mL)
• \( V2 \) — Final volume after dilution (mL)

Explanation: The equation calculates how many times the original solution has been diluted by comparing the final volume to the initial volume.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in chemistry, biology, medicine, and various industrial applications where precise concentrations are required.

4. Using the Calculator

Tips: Enter both volumes in milliliters (mL). The initial volume (V1) should be the volume before dilution, and the final volume (V2) should be the volume after dilution.

5. Frequently Asked Questions (FAQ)

Q1: What does a dilution factor of 10 mean?
A: A DF of 10 means the original solution was diluted 10 times (1 part original solution + 9 parts diluent).

Q2: How is dilution factor related to concentration?
A: The concentration after dilution is the original concentration divided by the dilution factor.

Q3: Can I use different units for V1 and V2?
A: No, both volumes must be in the same units (typically mL) for the calculation to be accurate.

Q4: What if my dilution factor is less than 1?
A: A DF < 1 indicates concentration rather than dilution, which is physically impossible unless you're removing solvent.

Q5: How do I prepare a specific dilution?
A: First calculate the required volumes using the DF, then add (DF-1) × V1 of diluent to V1 of stock solution.
