How to Dilute a Base
Formula
C₁V₁ = C₂V₂
Solving for C₂: C₂ = C₁V₁ / V₂
Where:
Concentrated bases like NaOH are corrosive. Use caution and appropriate PPE.
计算示例
Dilute 20 mL of 6 M NaOH to a final volume of 500 mL.
- 01C₂ = C₁V₁ / V₂
- 02C₂ = (6 × 20) / 500
- 03C₂ = 120 / 500
- 04C₂ = 0.24 M
常见问题
Is diluting a base exothermic?
Yes, dissolving concentrated bases in water releases heat. Add concentrated base slowly to water while stirring to dissipate heat.
Can I dilute any base this way?
Yes, C₁V₁ = C₂V₂ works for any solution dilution. For solid bases, dissolve first to get a stock solution, then dilute.
How do I prepare a specific volume of dilute base?
Calculate V₁ = C₂V₂/C₁ to find how much concentrated base to use, then add water to reach V₂.
