1. What is the Dilution Equation?

The dilution equation calculates the final concentration of a solution after dilution. It is based on the principle of conservation of mass, where the amount of solute remains constant before and after dilution.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

• \( C_f \) — Final concentration
• \( C_i \) — Initial concentration
• \( V_i \) — Initial volume
• \( V_f \) — Final volume

Explanation: The equation calculates the new concentration after adding solvent to a solution, maintaining the same amount of solute.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in laboratory settings, pharmaceutical preparations, and various scientific experiments where precise concentrations are required.

4. Using the Calculator

Tips: Enter initial concentration, initial volume, and final volume. All values must be positive numbers. The calculator will compute the final concentration after dilution.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for concentration?
A: You can use any consistent units (mg/mL, M, %, etc.) as long as initial and final concentrations use the same units.

Q2: What if I need to calculate initial concentration instead?
A: The equation can be rearranged: \( C_i = C_f \times \frac{V_f}{V_i} \)

Q3: Can this calculator handle different volume units?
A: Yes, as long as both volume measurements use the same units (mL, L, etc.).

Q4: What is the dilution factor?
A: The dilution factor is \( \frac{V_f}{V_i} \), representing how many times the original solution was diluted.

Q5: Are there limitations to this equation?
A: This equation assumes ideal solutions and complete mixing. It may not account for volume changes due to molecular interactions in some cases.
