0"Equivalent weight is that part of a chemical species which combines or replaces 1.008 gram of Hydrogen atom, 8 gram of Oxygen atom or 35.5 gram of Chlorine atom in a chemical reaction."
The mathematical formula to calculate Equivalent Weight
Equivalent Weight = (Molecular Wt / n-factor)
n-factor for acid is defined as number replaceable acidic hydrogen present in the acid.
n-factor for the base is defined as number replaceable hydroxyl ion furnished by the base.
n-factor for a redox agent is defined as the number of net electron transfer during the redox process
n-factor for salt is defined as the sum of total positive or negative charge present on the constituent ion in the salt.
