1. What is the Dilution Equation?

The dilution equation \( C_2 = C_1 \times \frac{V_1}{V_2} \) describes how the concentration of a solution changes when it is diluted. This fundamental principle in chemistry and physiology allows you to calculate the new concentration after adding solvent to an existing solution.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

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

Explanation: The equation shows that concentration is inversely proportional to volume when the amount of solute remains constant.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in laboratory work, medical preparations, and industrial processes where precise concentrations are required.

4. Using the Calculator

Tips: Enter all values in the appropriate units (M for concentration, L for volume). All values must be positive numbers. The calculator will compute the final concentration after dilution.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units with this calculator?
A: The calculator expects molarity (M) for concentration and liters (L) for volume. Convert your units before entering values.

Q2: What if my final volume is less than initial volume?
A: This would represent concentration rather than dilution, but the equation still holds mathematically.

Q3: Does this account for volume changes due to mixing?
A: This assumes ideal behavior where volumes are additive. For precise work, consider actual measured volumes.

Q4: Can I use this for serial dilutions?
A: For serial dilutions, you would need to apply this calculation sequentially for each dilution step.

Q5: How precise are the results?
A: Results are rounded to 4 decimal places. Precision depends on your input measurements.
