1. What Is The Dilution Formula?

The dilution formula calculates the final volume needed when diluting a solution from one concentration to another. It's based on the principle that the amount of solute remains constant during dilution.

2. How Does The Calculator Work?

The calculator uses the dilution formula:

Where:

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

Explanation: The formula maintains the product of concentration and volume constant before and after dilution.

3. Importance Of Dilution Calculations

Details: Accurate dilution calculations are essential in laboratory work, pharmaceutical preparations, chemical manufacturing, and various scientific applications where precise concentrations are required.

4. Using The Calculator

Tips: Enter initial volume in mL, initial and final concentrations in appropriate units. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What if I need to calculate the dilution factor instead?
A: The dilution factor is simply C₁/C₂, which represents how many times the original solution is diluted.

Q2: Can this formula be used for serial dilutions?
A: Yes, but you would need to apply the formula sequentially for each dilution step in a series.

Q3: What concentration units should I use?
A: The units for C₁ and C₂ must be the same (e.g., both in mg/mL, M, %, etc.) for the calculation to be valid.

Q4: Does this work for any type of concentration measurement?
A: Yes, as long as the concentration units are consistent and the dilution doesn't involve chemical reactions that change the nature of the solute.

Q5: What if I need to calculate the amount of diluent to add?
A: Subtract the initial volume (V₁) from the final volume (V₂) to determine how much diluent to add: V_diluent = V₂ - V₁.
