1. What is the Dilution Equation?

Definition: The dilution equation \( C1 \times V1 = C2 \times V2 \) describes the relationship between concentrations and volumes before and after a dilution.

Purpose: It helps scientists, chemists, and laboratory technicians calculate how to prepare solutions of desired concentrations from stock solutions.

2. How Does the Dilution Calculator Work?

The calculator uses the fundamental dilution formula:

Where:

• \( C1 \) — Initial concentration (units)
• \( V1 \) — Initial volume (units)
• \( C2 \) — Final concentration (units)
• \( V2 \) — Final volume (units)

Explanation: The product of initial concentration and volume equals the product of final concentration and volume. You can solve for any one variable if the other three are known.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential for preparing solutions in chemistry, biology, medicine, and various industrial processes.

4. Using the Calculator

Tips: Enter any three known values and leave one field empty (the one you want to calculate). The calculator will solve for the missing value.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: Use consistent units for concentration (e.g., M, mg/mL) and volume (e.g., L, mL) throughout the calculation.

Q2: Can I use this for serial dilutions?
A: This calculates single dilutions. For serial dilutions, you'll need to perform multiple calculations.

Q3: Does this account for mixing volumes?
A: This assumes ideal behavior where volumes are additive. For precise work, consult solution chemistry references.

Q4: What if I get a negative result?
A: All inputs must be positive numbers. Check your values if you get unexpected results.

Q5: How precise are the results?
A: Results are precise to 3 decimal places, but your actual precision depends on measurement accuracy.
