1. What is a Diluted Solution Calculator?

Definition: This calculator determines the concentration of a solution after dilution based on the initial concentration, initial volume, and final volume.

Purpose: It helps chemists, biologists, and laboratory technicians prepare solutions with precise concentrations for experiments and procedures.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

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

Explanation: The formula maintains that the amount of solute remains constant before and after dilution, only the volume changes.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are crucial for preparing solutions with correct concentrations, ensuring experimental reproducibility and safety.

4. Using the Calculator

Tips: Enter the initial concentration (in any units), initial volume (in liters), and final volume (in liters). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for concentration?
A: Any consistent units can be used (M, mM, %, etc.) as long as the same units are used for both C₁ and C₂.

Q2: Can I use different volume units?
A: Yes, as long as both V₁ and V₂ use the same units (mL, L, etc.).

Q3: What if I know C₂ but need to find V₂?
A: Rearrange the formula: \( V_2 = \frac{C_1 \times V_1}{C_2} \).

Q4: Does this work for serial dilutions?
A: For serial dilutions, apply the formula sequentially for each dilution step.

Q5: How precise should my measurements be?
A: Precision depends on your application. Analytical work typically requires high-precision measurements (±0.01 mL).
