1. What is the Dilution Equation?

The dilution equation \( C_1 \times V_1 = C_2 \times V_2 \) describes the relationship between concentrations and volumes before and after a dilution. It's based on the principle of mass conservation, where the amount of solute remains constant before and after dilution.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

\[ C_1 \times V_1 = C_2 \times V_2 \]

Where:

\( C_1 \) — Initial concentration (mol/L)
\( V_1 \) — Initial volume (L)
\( C_2 \) — Final concentration (mol/L)
\( V_2 \) — 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 in chemistry, biology, medicine, and many industrial processes where precise concentrations of solutions are required.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units with this calculator?
A: The calculator uses mol/L for concentration and L for volume by default. You can use any consistent units, but all concentrations must be in the same unit and all volumes in the same unit.

Q2: Why does the equation work?
A: The equation works because the amount of solute (number of moles) remains constant during dilution. The product C×V represents the amount of solute.

Q3: What if I need to do serial dilutions?
A: For serial dilutions, apply the equation sequentially for each dilution step, using the previous step's final concentration as the next step's initial concentration.

Q4: Can this be used for percent solutions?
A: Yes, as long as the concentration units are consistent (e.g., % w/v for both C1 and C2).

Q5: What's the difference between dilution and concentration?
A: Dilution is adding solvent to decrease concentration, while concentration is removing solvent to increase concentration. The same equation applies to both processes.
