Question

Molar ionic conductivities of a bivalent electrolyte are 57 and 73. The molar conductivity of the solution will be

• A. $130Scm^{2}mol^{- 1}$
• B. $65Scm^{2}mol^{- 1}$
• C. $260Scm^{2}mol^{- 1}$
• D. $187Scm^{2}mol^{- 1}$

Answer 1

Answer: (A)

$130Scm^{2}mol^{- 1}$

Answer 2

$\Lambda_{m}^{0} = 57 + 73 = 130Scm^{2}mol^{- 1}.$
