Using Kohlrausch law, calculate Lambda0 ...

Using Kohlrausch law, calculate `Lambda_0` for acetic acid, if `Lambda_0` value for hydrochloric acid, sodium chloride and sodium acetate are respectively 426, 126 and 91 `S cm^(2) mol^(-1).`

Text Solution

Verified by Experts

`Lambda_(0)` of acetic acid `= Lambda_(0)` of `CH_(3)CO O +Lambda_(0)` of `H^(+)`
`= Lambda_(0)` of HCl `+ Lambda_(0)` of `CH_(3) C O Ona-Lambda_(0)` of NaCl
`= 426 + 91 - 126 = 391 S cm^(2) mol^(-1)`.
