Understanding HCl Dilution Calculations
The calculator relies on a fundamental chemistry relationship:
Dilution Formula
C1V1=C2V2
Where:
- C₁ = Initial concentration
- V₁ = Initial volume
- C₂ = Final concentration
- V₂ = Final volume
This formula assumes that the number of moles remains constant during dilution.
For final molarity calculations, the calculator rearranges the formula to solve for concentration.
Practical Example 1: Preparing a Laboratory Solution
A laboratory technician needs to prepare 500 mL of 1 M HCl using a 12 M stock solution.
Inputs
- Stock Concentration: 12 M
- Target Concentration: 1 M
- Final Volume: 500 mL
Results
The calculator determines:
- Required volume of concentrated HCl
- Amount of water needed
This allows the technician to prepare the solution quickly and accurately.
Practical Example 2: Determining Final Concentration
A student uses:
- 20 mL of 6 M HCl
- Dilutes it to 200 mL
The calculator instantly calculates the resulting molarity.
This helps verify whether the prepared solution meets the requirements of the experiment.
