The molar conductance of a solution of A...

The molar conductance of a solution of `AlCl_(3)` in found to be 130 mho `cm^(2) "mol"^(-1)` at 298K.
What would be its equivalent conductance at the same temperature ?

Text Solution

Verified by Experts

`:.` Al forms `Al^(3+) ` ions
`:.` 1 mole of Al is equivalent to 3F of charge.
Hence, equivalent conductance of Al
`= 3 xx `molar conductance `= 3 xx130 `
= 390 mho `cm^(2) "g-equiv"^(-1)`
