Normality Calculator
Calculate normality (N) of a solution. Normality = equivalents of solute / liters of solution
Normality: N = equivalents / L
Common n-Factors:
HCl, HNO3: n = 1
H2SO4: n = 2
H3PO4: n = 3
NaOH: n = 1

Formula:
N = Equivalents / Volume (L)
N = M x n-factor
What is Normality?
Normality (N) is a measure of concentration that expresses gram equivalent weight of solute per liter of solution. It is related to molarity by the n-factor (equivalence factor), which represents the number of H+ ions (for acids), OH- ions (for bases), or electrons transferred (for redox reactions). Normality is particularly useful in acid-base titrations and redox reactions where equivalent weights are important.
