Features of Normality
- Symbol: N (Normal)
- Units: equivalents per liter (eq/L)
- Focuses on reactive capacity
- Essential for titration calculations
The Normality Formula
The Normality calculation relies on a simple formula: N = Weight of Solute (g) / (Equivalent Weight of Solute (g/eq) × Volume of Solution (L))
Basic Formula:
Normality (N) = Mass of Solute (g) / (Equivalent Weight × Volume in Liters)Alternative Formula:
Normality (N) = Molarity × Number of EquivalentsAdvantages of Using Our Normality Calculator

Frequently Asked Questions
What’s the difference between normality and molarity?
Normality uses a concept called an equivalence factor, whereas molarity simply counts molecules. Normality considers the reactive capacity of the solute.
Can normality be higher than molarity?
Yes, when a compound has multiple reactive units. For example, H₂SO₄ has a normality twice its molarity because it can donate 2 H⁺ ions.
Why is normality important in titrations?
The equivalent of an acid or base is how many protons are donated or accepted, making normality perfect for calculating neutralization points.
