Neutralization Calculator Calculate the volume or concentration of acid or base needed to neutralize a solution using the neutralization formula. — free online calculator.

Formula

N₁V₁ = N₂V₂
  • Neutralization Calculator calculates its result from N2, V2. It uses the formula N₁V₁ = N₂V₂. Change any input to recalculate the result instantly.
  • The main inputs are Normality of Acid, Volume of Acid, Normality of Base. Enter them in the units and format shown in the calculator.
  • Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
  • Changing any input above recalculates the result with the same calculation engine used by this page.

Example: Neutralization

Inputs
  • Normality of Acid: 1 N₁
  • Volume of Acid: 25 V₁
  • Normality of Base: 0.5 N₂

Using N2 = 2, V2 = 3, the calculated result is 6.
