Neutralization Reaction Calculator

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

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  + 2H₂O 
• H₃PO₄ + 3NaOH → Na₃PO₄ + 3H₂0 
• 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
