Chemical Solution Mixer
Calculate dilution ratios for mixing chemical solutions.
Use the C1V1 = C2V2 dilution equation.
Solution Mixing Result
The dilution equation is used to calculate how to make a solution of a desired concentration from a more concentrated stock solution.
Formula:
C1 × V1 = C2 × V2
Where:
- C1 = concentration of stock solution
- V1 = volume of stock solution needed
- C2 = desired final concentration
- V2 = desired final volume
Example: Make 500 mL of 10% bleach from 100% bleach:
- C1 = 100%, V1 = ?, C2 = 10%, V2 = 500 mL
- V1 = (10 × 500) / 100 = 50 mL of bleach
- Add 450 mL of water to reach 500 mL total
Common dilutions:
| Use | Concentration |
|---|---|
| Household bleach | 5–6% |
| Disinfecting surfaces | 0.5% bleach |
| Isopropyl alcohol | 70% (optimal) |
| Hydrogen peroxide | 3% (standard) |
