1. What is the Dilution Formula?

The dilution formula calculates the final concentration of a solution after dilution. It's based on the principle that the amount of solute remains constant before and after dilution.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

• \( C_1 \) — Initial concentration (%)
• \( V_1 \) — Initial volume (L)
• \( V_2 \) — Final volume (L)
• \( C_2 \) — Final concentration (%)

Explanation: The formula 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 various industries for preparing solutions of desired concentrations.

4. Using the Calculator

Tips: Enter all values in the specified units. Ensure all values are positive numbers. The calculator will compute the final concentration after dilution.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different units for volume?
A: Yes, as long as V1 and V2 use the same units (both in mL, both in L, etc.), the calculation will be correct.

Q2: What if my final volume is less than initial volume?
A: This would represent concentration, not dilution. The formula still works mathematically but may not represent a physical dilution process.

Q3: How precise should my measurements be?
A: Precision depends on your application. For most laboratory work, 4 significant figures is sufficient.

Q4: Does this work for any concentration unit?
A: Yes, as long as C1 and C2 use the same units (%, M, mg/mL, etc.), the formula applies.

Q5: What about serial dilutions?
A: For serial dilutions, apply the formula sequentially for each dilution step.
