Neutralization Calculator – Easy pH Calculations

This tool will help you calculate the exact amount of acid or base needed for neutralization.

Neutralization Calculator Explanation

This calculator helps you determine the volume of base required to neutralize a given volume of acid, based on their molarities.

How to Use:

  1. Enter the molarity of the acid in the first input box.
  2. Enter the volume of the acid in liters in the second input box.
  3. Enter the molarity of the base in the third input box.
  4. Enter the volume of the base in liters in the fourth input box.
  5. Click the ‘Calculate’ button to see the result.

How it Calculates:

This calculator uses the formula n = M * V where:

  • M is the molarity of the solution (in mol/L)
  • V is the volume of the solution (in L)
  • n is the number of moles of the solute.

The neutralization point is calculated by ensuring the moles of acid and base are equal. Hence, the volume required for neutralization is derived by balancing the equation.


This calculator assumes that the neutralization reaction follows a simple one-to-one mole ratio (e.g., HCl and NaOH). For reactions with different stoichiometric ratios, the calculation would need to be adjusted accordingly.
