Dilution Equation:
| From: | To: |
The dilution equation \( C_i V_i = C_f V_f \) is a fundamental principle in chemistry that describes how the concentration of a solution changes when it is diluted. It states that the product of the initial concentration and volume equals the product of the final concentration and volume after dilution.
The calculator uses the dilution equation:
Where:
Explanation: The equation maintains that the amount of solute remains constant before and after dilution, allowing calculation of any one variable if the other three are known.
Details: This equation is crucial for preparing solutions of desired concentrations in laboratories, pharmaceutical preparations, and various chemical processes. It ensures accurate and reproducible results in experimental work.
Tips: Enter all four values (initial concentration, initial volume, final concentration, final volume) in their respective units. The calculator will verify if the dilution equation holds true for the given values.
Q1: What units should I use for concentration?
A: You can use any consistent units for concentration (M, mM, %, etc.) as long as both initial and final concentrations use the same units.
Q2: Can I use different volume units?
A: Yes, but both volume measurements must use the same units (mL, L, etc.) for the equation to work correctly.
Q3: What if my equation doesn't balance?
A: This indicates an error in measurement, calculation, or that additional factors (like evaporation or reaction) may be affecting your solution.
Q4: Does this work for serial dilutions?
A: Yes, the equation can be applied sequentially for multiple dilution steps in serial dilution procedures.
Q5: Are there limitations to this equation?
A: The equation assumes ideal behavior and that no chemical reactions occur during dilution. It may not be accurate for very concentrated solutions.
