1. What is Molarity Dilution?

Molarity dilution refers to the process of reducing the concentration of a solution by adding more solvent. The amount of solute remains the same, but the total volume increases, resulting in a lower molarity.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

• \( M_1 \) — Initial molarity (mol/L)
• \( V_1 \) — Initial volume (mL)
• \( V_2 \) — Final volume after dilution (mL)
• \( M_2 \) — Final molarity (mol/L)

Explanation: The equation shows that the product of initial molarity and volume equals the product of final molarity and volume (conservation of moles).

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in laboratory work, pharmaceutical preparations, and chemical manufacturing to achieve desired solution concentrations.

4. Using the Calculator

Tips: Enter initial molarity in mol/L, initial and final volumes in mL. All values must be positive numbers. The final volume must be greater than the initial volume for dilution.

5. Frequently Asked Questions (FAQ)

Q1: Can I use this for concentrated solutions?
A: Yes, but for very concentrated solutions, volume changes due to mixing might affect accuracy.

Q2: What if my final volume is less than initial volume?
A: That would represent concentration, not dilution. This calculator is for dilution only.

Q3: Does temperature affect molarity?
A: Yes, molarity is temperature-dependent because volume changes with temperature. For precise work, specify temperature.

Q4: Can I use different volume units?
A: The calculator uses mL, but any consistent volume units will work as long as both V₁ and V₂ use the same unit.

Q5: How precise should my measurements be?
A: Precision depends on your needs. For analytical work, use volumetric flasks and precise measurements.
