1. What is PPM Dilution?

PPM (parts per million) dilution refers to the process of reducing the concentration of a substance in a solution by adding more solvent. The dilution formula calculates the new concentration after dilution.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

• \( C_1 \) — Initial concentration (ppm)
• \( V_1 \) — Initial volume (mL)
• \( V_2 \) — Final volume after dilution (mL)
• \( C_2 \) — Final concentration (ppm)

Explanation: The formula shows that the final concentration is directly proportional to the ratio of initial to final volumes.

3. Importance of PPM Calculations

Details: Accurate dilution calculations are essential in chemistry, environmental science, medicine, and manufacturing to achieve precise concentrations of solutions.

4. Using the Calculator

Tips: Enter all values in the same units (ppm for concentration, mL for volume). Ensure all values are positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What does ppm mean?
A: Parts per million (ppm) is a unit of concentration representing 1 part of substance per 1 million parts of solution.

Q2: Can I use different volume units?
A: Yes, as long as V1 and V2 are in the same units (both mL, both L, etc.).

Q3: What if my final volume is less than initial volume?
A: This would represent concentration, not dilution. The calculator still works mathematically but may not reflect physical reality.

Q4: How precise should my measurements be?
A: For critical applications, use precise measurements (at least 3 significant figures) and calibrated equipment.

Q5: Does temperature affect the calculation?
A: The calculation assumes volumes are additive at constant temperature. For very precise work, consider temperature effects on volume.
