公式

How to Dilute a Base

Formula

C₁V₁ = C₂V₂

Solving for C₂: C₂ = C₁V₁ / V₂

Where:

  • C₁ = initial concentration
  • V₁ = volume of concentrated base
  • C₂ = final concentration
  • V₂ = final total volume
  • 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.

    1. 01C₂ = C₁V₁ / V₂
    2. 02C₂ = (6 × 20) / 500
    3. 03C₂ = 120 / 500
    4. 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.
