Step 1 :
Formula weight of KOH =56.108
Acidity of KOH = 1
Step 2 :
Substitute the values in the corresponding formula.
Equivalent weight of base=Molecular weight of baseAcidity of baseEquivalent weight of base=Molecular weight of baseAcidity of base
Equivalent weight of base=56.1081Equivalent weight of base=56.1081
$Equivalent weight of base = 56.108
0.12375 gm of KOH = 0.624 gm of the acid
So 56.108 gm of KOH = 0.624×56.1080.123750.624×56.1080.12375 gm of the acid
= 28.278 gm of the acid = 1 gm equivalent of the acid.
that is 1 gm equivalent of the acid = 28.278 gm of the acid
The equivalent weight of the given base KOH = 56.108gm
