1. What is the Dilution Equation?

The dilution equation (C1V1 = C2V2) describes how the concentration of a solution changes when it is diluted. It's based on the principle of conservation of mass - the amount of solute remains the same 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 (mL)
• \( C_2 \) — Final concentration (mol/L)
• \( V_2 \) — Final volume (mL)

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

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 three values (C1, V1, V2) in their respective units. All values must be positive numbers. The calculator will compute the final concentration (C2).

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units for volume?
A: Yes, as long as V1 and V2 are in the same units. The calculator currently uses mL by default.

Q2: What if my final volume is less than initial volume?
A: That would represent concentration, not dilution, and the final concentration would be higher than the initial concentration.

Q3: Does this work for any concentration unit?
A: Yes, as long as C1 and C2 use the same units (mol/L, g/L, %, etc.).

Q4: How precise are the calculations?
A: The calculator provides results to 4 decimal places, but actual precision depends on your measurement accuracy.

Q5: Can I calculate initial concentration instead?
A: Yes, you can rearrange the equation to solve for any variable if you know the other three.
