1. What is Molarity Dilution?

Molarity dilution refers to the process of reducing the concentration of a solution by adding more solvent. The dilution ratio describes how much the original solution is being diluted.

2. How Does the Calculator Work?

The calculator uses the dilution formula:

Where:

• \( M1 \) — Initial molarity (mol/L)
• \( ratio \) — Dilution ratio (dimensionless)
• \( M2 \) — Final molarity after dilution (mol/L)

Explanation: The formula shows that the final concentration is inversely proportional to the dilution ratio.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in chemistry labs, pharmaceutical preparations, and biological experiments to achieve desired concentrations.

4. Using the Calculator

Tips: Enter the initial molarity in mol/L and the dilution ratio (e.g., for a 1:10 dilution, enter 10). Both values must be positive numbers.

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 (V2/V1), while dilution factor is its reciprocal (V1/V2).

Q2: How do I prepare a 1:100 dilution?
A: Mix 1 part of the original solution with 99 parts of solvent (total 100 parts).

Q3: Can I use this for serial dilutions?
A: Yes, but you need to apply the calculator sequentially for each dilution step.

Q4: Does this work for percent concentration?
A: The same principle applies, but this calculator specifically calculates molarity.

Q5: What if my ratio is less than 1?
A: Ratios <1 would represent concentration, not dilution, which isn't the intended use of this calculator.
