The molar conductivity at infinite dilution of barium chloride, sulphuric arid and hydrochloric acid are 280 , 860 426 Scm 2 mol - 1 respectively. The molar conductivity at infinite dilution of barium sulphate is ___ Scm 2 mol - 1 ( Round off to the Nearest Integer).

Correct answer

0

Step-by-step solution

From Kohlrausch's law Λ m ∞ BaSO 4 = λ m ∞ Ba 2 + + λ m ∞ SO 4 2 - Λ m ∞ BaSO 4 = Λ m ∞ BaCl 2 + Λ m ∞ H 2 SO 4 - 2 Λ m ∞ ( HCl ) = 280 + 860 - 2 ( 426 ) = 288   Scm 2   mol - 1
