1. What is the Dilution Formula?

The dilution formula calculates the final concentration of a solution after dilution. It's based on the principle of conservation of mass, where the amount of solute remains constant before and after dilution.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

• \( ppm_f \) — Final concentration in parts per million
• \( ppm_i \) — Initial concentration in parts per million
• \( V_i \) — Initial volume in liters
• \( V_f \) — Final volume in liters

Explanation: The formula calculates the new concentration after diluting an initial volume of solution to a larger final volume.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are crucial in chemistry, biology, environmental science, and industrial processes for preparing solutions of specific concentrations from stock solutions.

4. Using the Calculator

Tips: Enter initial concentration in ppm, initial volume in liters, and final volume in liters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What does ppm stand for?
A: PPM stands for parts per million, which represents one part of solute per million parts of solution.

Q2: Can I use different volume units?
A: Yes, as long as you use the same units for both initial and final volumes (mL, L, etc.).

Q3: What if my final volume is smaller than initial volume?
A: This would represent concentration rather than dilution, and the formula would still work mathematically.

Q4: Does this formula work for all types of solutions?
A: The formula works for ideal solutions where volume changes are additive. For non-ideal solutions, corrections may be needed.

Q5: How accurate is this calculation?
A: The calculation is mathematically exact. Accuracy depends on the precision of your measurements and the quality of your equipment.
