1. What is the Dilution Equation?

The dilution equation (C1V1 = C2V2) describes how the concentration of a solution changes when it is diluted with solvent. It's a fundamental concept in chemistry used to prepare solutions of desired concentrations.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

• \( C_1 \) — Initial concentration (mol/L)
• \( V_1 \) — Initial volume (L)
• \( V_2 \) — Final volume after dilution (L)
• \( C_2 \) — Final concentration (mol/L)

Explanation: The equation shows that concentration is inversely proportional to volume when the amount of solute remains constant.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential for preparing standard solutions, performing titrations, and conducting experiments that require precise concentrations.

4. Using the Calculator

Tips: Enter all values in consistent units (mol/L for concentration, liters for volume). Ensure all values are positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I use different volume units?
A: Yes, as long as V1 and V2 are in the same units (e.g., both in mL or both in L).

Q2: What if I need to find V1 instead of C2?
A: The equation can be rearranged to \( V_1 = \frac{C_2 \times V_2}{C_1} \).

Q3: Does temperature affect dilution calculations?
A: Temperature affects solution density but not molarity calculations unless volume changes significantly with temperature.

Q4: How accurate are dilution calculations?
A: The calculation is mathematically exact, but practical accuracy depends on measurement precision of volumes and concentrations.

Q5: Can this be used for serial dilutions?
A: Yes, but for serial dilutions you would apply the equation sequentially for each dilution step.
