Question

Give formula for calculation of equivalent weight of the compound.

Answer 1

Equivalent weight of acid = molecular weight of acid/basicity

For example, Equivalent weight of H₂SO₄ = \(\frac{98}{2}\) = 49 g/eq 

Equivalent weight of base = molecular weight of base/acidity

Example, Equivalent weight of NaOH = \(\frac{40}{1}\) = 40 g/eq 

Equivalent weight of salt = molecular weight of salt/charge present on ionic form

Example, Equivalent weight of Na₂CO₃= \(\frac{106}{2}\) = 53 g/eq
