1. What is the Dilution Equation?

The dilution equation \( C_2 = C_1 \times \frac{V_1}{V_2} \) calculates the final concentration of a solution after dilution, where \( C_1 \) is the initial concentration, \( V_1 \) is the initial volume, and \( V_2 \) is the final volume after dilution.

2. How Does the Calculator Work?

The calculator uses the dilution equation:

Where:

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

Explanation: The equation maintains the conservation of mass principle, where the amount of solute remains constant before and after dilution.

3. Importance of Dilution Calculations

Details: Accurate dilution calculations are essential in laboratory work, pharmaceutical preparations, and clinical settings to achieve desired concentrations of solutions.

4. Using the Calculator

Tips: Enter all values in their respective units (mg/mL for concentrations, mL for volumes). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can this calculator be used for other concentration units?
A: Yes, as long as you maintain consistent units for C1 and C2 (e.g., both in μg/mL or both in g/L).

Q2: What if I know C2 and need to find V2?
A: The equation can be rearranged to \( V_2 = \frac{C_1 \times V_1}{C_2} \) for that calculation.

Q3: How precise should my measurements be?
A: Precision depends on your application. For critical applications, use volumetric glassware and measure carefully.

Q4: Does temperature affect the dilution?
A: Temperature can affect volume measurements but not the mass of solute. For precise work, measure at controlled temperatures.

Q5: Can I dilute with any solvent?
A: Yes, as long as the solute is soluble in the solvent and the solvent doesn't react with the solute.
