Dilution law (moles of solute constant) (For same solute before and after dilution: initial moles = final moles → C₁V₁ = C₂V₂)
jee-mainjee-advancedneet-ug
For same solute before and after dilution: initial moles = final moles → C₁V₁ = C₂V₂ (consistent volume units)
What each symbol means
| Symbol | What it stands for |
|---|---|
| C_1 | Initial molarity |
| C_2 | Final molarity |
| V_1 | Initial solution volume |
| V_2 | Final solution volume |
When to use this
Only solute amount fixed; volumes must be in same units (both mL or both L). Assumes additive volumes unless problem states otherwise.
