1. What is the Dilution Formula?

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

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

• \( C_1 \) — Initial concentration (M)
• \( V_1 \) — Initial volume (L)
• \( V_2 \) — Final volume after dilution (L)
• \( C_2 \) — Final concentration (M)

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

3. Importance of Dilution Calculations

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

4. Using the Calculator

Tips: Enter all values in consistent units (M for concentration, L for volume). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different volume units?
A: Yes, as long as both V₁ and V₂ are in the same units (mL, L, etc.), the calculation will be correct.

Q2: What if my final volume is less than initial volume?
A: This would represent concentration, not dilution. The formula still works mathematically but may not represent a physical dilution process.

Q3: Does this work for any concentration unit?
A: Yes, as long as C₁ and C₂ use the same units (M, mM, %, etc.).

Q4: How precise should my measurements be?
A: Precision depends on your needs. For most laboratory work, 3-4 significant figures are appropriate.

Q5: Can this calculate reverse dilutions?
A: Yes, you can rearrange the formula to solve for any variable if you know the other three.
