Neutralization Reaction Calculator

The acid-base neutralization Reaction Calculator is used for the estimation of the equivalent weight of acid or base. Users can switch to find any of the four mentioned values.

  • Normality
  • Weight of acid or base
  • Volume of acid or base 
  • Equivalent weight

The neutralization equation used in this calculator requires volume and weight of acid or base along with normality. 

What is a neutralization reaction?

The reaction of acid and base which produces salt and water is called a neutralization reaction.

I.e 

Acid + Base = Salt + water

equivalent weight of acid or base

The method is based on the fact that one gram equivalent of the acid completely neutralizes one gram equivalent of the base and vice-versa. 

Examples of neutralization reaction:

  • Ca(OH)2 + H2CO3  → CaCO3  + 2H2
  • H3PO4 + 3NaOH → Na3PO4 + 3H2
  • NaOH + H2SO4 → Na2SO4 + H2O

Equivelent weight formula:

Equation to find equivalent weight is:

E.W = weight / (volume * normality)

How to find equivalent weight?

Example:

Calculate the equivalent weight of acid of volume 25. The weight of acid is 15 grams and normality is 20

Solution:

Step 1: Identify the values.

Volume = 25

Weight  = 15

Normality = 20

Step 2: Use the values on the formula.

Equivalent weight = weight / (volume * normality)

= 15 / (25 * 20)

= 0.0300
