1. What is Dilution?

Dilution is the process of reducing the concentration of a solute in solution by adding more solvent. It's a fundamental technique used in chemistry, biology, and medicine.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

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

Explanation: The equation states that the product of initial concentration and volume equals the product of final concentration and volume after dilution.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential for preparing solutions of desired concentrations, which is critical in laboratory work, medical treatments, and industrial processes.

4. Using the Calculator

Tips: Enter three known values (leaving one field empty) to calculate the unknown value. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between dilution and concentration?
A: Dilution reduces concentration by adding solvent, while concentration increases the solute-to-solvent ratio, typically by removing solvent.

Q2: How do I prepare a 1:10 dilution?
A: Mix 1 part stock solution with 9 parts diluent (total 10 parts). For example, 1 mL stock + 9 mL water.

Q3: Can I dilute with any solvent?
A: The solvent should be compatible with your solute. For aqueous solutions, distilled water is typically used.

Q4: Why does the equation work?
A: The equation conserves the amount of solute (moles), which remains constant during dilution.

Q5: How precise should my measurements be?
A: Precision depends on application. For medical or analytical work, use volumetric flasks for high precision.
