1. What is the Dilution Formula?

The dilution formula \( C1 \times V1 = C2 \times V2 \) is a fundamental equation in chemistry that relates the concentrations and volumes of a solution before and after dilution. It's based on the principle that the amount of solute remains constant during dilution.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

• \( C1 \) — Initial concentration (mol/L)
• \( V1 \) — Initial volume (L)
• \( C2 \) — Final concentration (mol/L)
• \( V2 \) — Final volume (L)

Explanation: The equation states that the product of initial concentration and volume equals the product of final concentration and volume after dilution.

3. Importance of Dilution Calculations

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

4. Using the Calculator

Tips: Enter any three known values (leaving one field empty or zero) to calculate the missing variable. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units with this calculator?
A: The calculator uses consistent units (mol/L for concentration, L for volume). Convert your values to these units before calculation.

Q2: What if I need to do serial dilutions?
A: For serial dilutions, apply the formula sequentially for each dilution step.

Q3: Does this work for percent solutions?
A: Yes, as long as you maintain consistent units (e.g., % w/v for all concentration values).

Q4: How precise should my measurements be?
A: Precision depends on your application. Analytical work typically requires more precise measurements than general lab work.

Q5: Can this be used for solid dilutions?
A: This formula is for liquid dilutions. For solid mixtures, different calculations are needed.
