Can anyone give me detailed information about n factor in elements, salts, acids, bases, and redox reactions.
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
http://www.askiitians.com/forums/Physical-Chemistry/19/59105/n-factor.htm
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
