Neutralization Calculator
Calculate the normality of a solution by entering the values below.
💡 Normality (N) = Weight of solute / (Volume of solvent × Equivalent weight)
How to use this calculator:
- Enter the weight of your solute (acid or base)
- Enter the volume of your solvent (typically water)
- Enter the equivalent weight of your substance or select a common substance from the dropdown
- Click "Calculate Normality" to determine the normality (N) of your solution
About Normality:
Normality is a measure of concentration equal to the gram equivalent weight per liter of solution. It's particularly useful in acid-base chemistry and neutralization reactions.
The formula for normality is:
Normality (N) = Weight of solute / (Volume of solvent × Equivalent weight)
This neutralization calculator is a tool that helps you analyze reactions in which acids and bases are neutralized. You can use it to find the normality of the solution, but also to calculate the equivalent weight of the analyzed substance. Read on to find the formula used by this neutralization reaction calculator, along with an example of application.
Neutralization reaction definition
A neutralization reaction is a chemical reaction, in which an acid and a base interact with each other. The result of this reaction is the formation of a salt. In the case of strong acids and bases, the essential reaction is the combination of hydrogen ions with hydroxyl ions to form water molecules.
Formula for normality
The equation for normality is:
normality = mass of solute / (volume of solvent * equivalent weight)
where:
normality— A value that measures the concentration of the substance (acid or base) in a dissolving liquid. It is measured in the unit N equivalent to eq/L.mass of solute— Weight of the substance of interest (acid or base), expressed in grams (g).volume of solvent— Volume of the liquid in which the substance is dissolved. It is typically measured in liters (L), but you may also use volume converter for volume-related conversions.equivalent weight— Equal to the molecular weight of the substance (acid or base) divided by its valence. You can easily find this value for most common substances. It is expressed in g/eq.

How to use the neutralization calculator
Determine the equivalent weight of your substance. For example, the equivalent weight of sodium chloride (NaCl) is equal to 58.443 g/eq.
Decide on the mass of your substance that you want to neutralize. Let’s assume you have 3 g of sodium chloride.
Choose the volume of the solvent (liquid). We can assume you want to dissolve your NaCl sample in 0.1 liters of water.
Use the normality equation:
normality = mass of solute / (volume of solvent * equivalent weight)normality = 3 g / (0.1 L * 58.443 g/eq) = 0.5133 eq/L = 0.5133 NYou can also spare yourself the calculations and simply use the neutralization calculator instead 😀
