Calculadora ácido-base

Calcula os mols e o volume de ácido necessários para neutralizar uma dada quantidade de base.

Introdução

Acid-Base Calculator — Calculate moles and volume of acid needed to neutralize a given amount of base. Enter Base concentration (mol/L), Base volume (L), Acid concentration (mol/L) to get an instant, accurate result.

Fórmula

Monoprotic neutralization stoichiometry: moles of acid = moles of base, so Cₐ × Vₐ = C_b × V_b — the calculator finds moles of base and the acid volume needed to neutralize it.

Passo a passo

  1. Enter the Base concentration (mol/L).
  2. Enter the Base volume (L).
  3. Enter the Acid concentration (mol/L).
  4. Click Calculate to see your result instantly.

Exemplo do mundo real

Example: With Base concentration (mol/L) = 0.1, Base volume (L) = 1, Acid concentration (mol/L) = 0.1, the Acid-Base Calculator gives Moles Base: 0.1, Moles Acid Needed: 0.1, Acid Volume Needed L: 1.

Perguntas Frequentes

Does this work for polyprotic acids or bases?
No, this assumes a 1:1 monoprotic reaction (one H⁺ neutralizes one OH⁻); polyprotic species (like H₂SO₄) require an extra stoichiometric factor.
What does "moles of acid needed" tell me?
It's the exact amount of acid required to reach the equivalence point, where moles of acid equal moles of base.
What inputs does the Acid-Base Calculator need?
You'll need to provide: Base concentration (mol/L), Base volume (L), Acid concentration (mol/L). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Acid-Base Calculator?
The Acid-Base Calculator applies the formula exactly as calculated — Monoprotic neutralization stoichiometry: moles of acid = moles of base, so Cₐ × Vₐ = C_b × V_b — the calculator finds moles of base and the acid volume needed to neutralize it. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Acid-Base Calculator free to use?
Yes, the Acid-Base Calculator is completely free, requires no signup, and runs instantly in your browser.

Sobre a Calculadora ácido-base

The Acid-Base Calculator uses a real, verifiable formula — Monoprotic neutralization stoichiometry: moles of acid = moles of base, so Cₐ × Vₐ = C_b × V_b — the calculator finds moles of base and the acid volume needed to neutralize it. — so results are accurate every time, not an approximation.
