About Solution Dilution Calculator
Understanding Solution Dilution
The concept of dilution dates back to ancient civilizations, with early alchemists and physicians using dilution techniques for medicines. The mathematical framework was formalized in the 18th century with the development of quantitative chemistry, particularly through the work of Antoine Lavoisier, often called the "father of modern chemistry."
Mathematical Foundation
C₁V₁ = C₂V₂
V₂ = (C₁V₁)/C₂
Dilution Factor = C₁/C₂ = V₂/V₁
- C₁ = Initial concentration
- V₁ = Initial volume
- C₂ = Final concentration
- V₂ = Final volume
Types of Dilutions
Serial Dilutions:
- Sequential dilution steps where each new solution is made from the previous dilution
- Each step maintains a consistent dilution factor
- Used in microbiology for bacterial culture counting
- Common ratios include 1:2 and 1:10
