1. What is Solution Dilution?

Solution dilution is the process of reducing the concentration of a solute in solution by adding more solvent. The dilution equation relates the concentrations and volumes before and after dilution.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

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

Explanation: The equation 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 the appropriate units (concentration in mol/L, volumes in liters). 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 work correctly.

Q2: What if I know C2 and need to find V2?
A: The equation can be rearranged to \( V_2 = \frac{C_1 \times V_1}{C_2} \) for that calculation.

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

Q4: Is temperature important in dilution calculations?
A: Temperature affects the volume slightly, but for most purposes at constant temperature, the calculation is accurate.

Q5: Can this be used for percent solutions?
A: Yes, the same equation works for any concentration units as long as C1 and C2 are in the same units.
