1. What is Simple Dilution?

Simple dilution is the process of reducing the concentration of a solute in solution by adding more solvent. The relationship between concentrations before and after dilution is linear when the dilution factor is known.

2. How Does the Calculator Work?

The calculator uses the simple dilution formula:

Where:

• \( C_1 \) — Initial concentration
• \( C_2 \) — Final concentration after dilution
• \( \text{ratio} \) — Dilution factor (e.g., 0.1 for 1:10 dilution)

Explanation: The final concentration is directly proportional to the initial concentration multiplied by the dilution ratio.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in laboratory work, pharmaceutical preparations, and any situation requiring precise concentration adjustments.

4. Using the Calculator

Tips: Enter the initial concentration and the dilution ratio. The ratio should be between 0 and 1 (e.g., 0.5 for 1:2 dilution, 0.1 for 1:10 dilution).

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between dilution ratio and dilution factor?
A: The dilution ratio is the ratio of final volume to initial volume (e.g., 1:10), while the dilution factor is the inverse (1/10 = 0.1) used in calculations.

Q2: How do I prepare a 1:100 dilution?
A: Mix 1 part stock solution with 99 parts diluent (total 100 parts). The ratio would be 0.01 in the calculator.

Q3: Can I use this for serial dilutions?
A: Yes, you can calculate each step sequentially by applying the ratio multiple times.

Q4: What units should I use?
A: The units will be the same for C1 and C2. Use consistent units (mg/mL, M, %, etc.) for both input and output.

Q5: Does this account for volume changes?
A: This simple calculation assumes the volumes are additive. For very precise work or non-aqueous solutions, more complex calculations may be needed.
