Question

in case of univalent electrolyte,the equivalent and molecular conductivities are_______​

Answer 1

In case of univalent electrolyte ,the equivalent and molecular conductivities are same.

Univalent electrolytes are the electrolytes in which one of each ion has a valence or charge, of 1, and, after dissociation , two ions are produced, such as Sodium chloride (NaCl) , $Na^{+}$ and $Cl^{-}$ each ion has valency of 1.

As we know, ∧м = ∧ ×  valency factor [ Where ∧м= molecular conductivity and ∧= Equivalent conductivity

and for univalent electrolyte valency factor = 1

∴ ∧м = ∧ × 1

⇒ ∧м = ∧

So, in case of univalent electrolyte, the equivalent and molecular conductivities are same.
