How to Dilute an Acid
Formula
C₁V₁ = C₂V₂
Solving for C₂: C₂ = C₁V₁ / V₂
Where:
Safety: Always add acid to water, never water to acid.
计算示例
Dilute 10 mL of 12 M HCl to a final volume of 1000 mL.
- 01C₂ = C₁V₁ / V₂
- 02C₂ = (12 × 10) / 1000
- 03C₂ = 120 / 1000
- 04C₂ = 0.12 M
常见问题
Why add acid to water?
Adding acid to water disperses the heat of dilution safely. Adding water to concentrated acid can cause violent boiling and spattering.
Does this work for all acids?
Yes, C₁V₁ = C₂V₂ applies to any dilution as long as no chemical reaction occurs during mixing.
Can I use this for serial dilutions?
Yes, apply the formula to each step sequentially or use C_final = C_initial × (V_transfer / V_total)^n for n identical steps.
