How to calculate chemical equivalent weight?

Answer 1

Good Question
Chemical equivalent weight = molecular weight for most of the chemical compounds.
for an acid, it is molecular weight by no. of hydrogen
HCl = one hydrogen = 36.5/1 = 36.5
for a base, it is molecular weight by no. OH
NaOH = 1 OH = 40/1 = 40
for salts, it s molecular weight by no. electrons involved during the chemical reaction
KMnO4 = 5 electrons involved = 158/5 = 31 nearly
