1. What is the Dilution Formula?

The dilution formula calculates the new concentration of a solution after it has been diluted. It's based on the principle that the amount of solute remains constant before and after dilution, only the volume changes.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

• \( C_1 \) — Initial concentration (molarity)
• \( V_1 \) — Initial volume
• \( C_2 \) — Final concentration after dilution
• \( V_2 \) — Final volume after dilution

Explanation: The formula 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 values in consistent units (M for concentration, L for volume). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different volume units?
A: Yes, as long as V₁ and V₂ use the same units (e.g., both in mL or both in L).

Q2: What if I know C₂ and need to find C₁?
A: The formula can be rearranged: \( C_1 = C_2 \times \frac{V_2}{V_1} \)

Q3: Does this work for percent concentrations?
A: Yes, the formula works for any concentration units as long as C₁ and C₂ use the same units.

Q4: What's the dilution factor?
A: The dilution factor is \( \frac{V_2}{V_1} \), representing how many times the solution was diluted.

Q5: How do serial dilutions work?
A: For serial dilutions, multiply the dilution factors at each step to get the overall dilution.
