Suggest a way to determine the Λ 0 m
Solution:
Water is a weak electrolyte. Its Λ 0 m
Λ m 0 ( H C l ) = Λ m 0 ( H + ) + Λ m 0 ( C l − )
Λ m 0 ( N a O H ) = Λ m 0 ( N a + ) + Λ m 0 ( O H − )
Λ m 0 ( N a C l ) = Λ m 0 ( N a + ) + Λ m 0 ( C l − )
Adding (i) and (ii) and subtracting (iii) we get
Λ m 0 ( H 2 O ) = Λ m 0 ( H + ) + Λ m 0 ( O H − )
= Λ m 0 ( H C l ) + Λ m 0 ( N a O H ) − Λ m 0 ( N a C l )
Adding (i) and (ii) and subtracting (iii) we get
