Equivalant weight is the ratio of atomic weight and a factor(say n-factor)

Equivalent weight = atomic weight/n-factor

In case acid/base the n-factor is basicity/acidity(i.e. number of dissociable H+

ions/number of dissociable ions and in case of oxidizing/reducing agents,n-factor is number of moles of electrons gained/lost per mole of oxidizing/reducing agents.

therefore in general we can write 

 

EQUIVALENT WEIGHT(E)=atomic or molecular weight

n-factor

for elements=atomic mass/valency

for salts=mol mass of comp/charge on cation or anoin

for acids/bases=mol mass/acidity or basicity

for redox reac.= mol mass/change in ox no. per mole
