1. What is the Dilution Equation?

The dilution equation (C₁V₁ = C₂V₂) describes how the concentration of a solution changes when it's diluted with solvent. It's fundamental in chemistry, biology, and medical laboratory work.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

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

Explanation: The equation maintains that the amount of solute remains constant before and after dilution.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential for preparing solutions of desired concentrations in laboratories, medical testing, and pharmaceutical preparations.

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 V₁ and V₂ are in the same units (both mL or both L), the calculation remains valid.

Q2: What if my final volume is less than initial volume?
A: This would represent concentration, not dilution. The calculator still works but gives a concentration factor rather than dilution factor.

Q3: Does this work for serial dilutions?
A: For serial dilutions, you need to apply the equation sequentially for each dilution step.

Q4: Are there limitations to this equation?
A: This assumes ideal solutions where volumes are perfectly additive, which may not be strictly true for all solutions.

Q5: How precise should my measurements be?
A: Precision depends on your application. Analytical work typically requires more precise measurements than general lab work.
