Calculate Lambda(m)^(@) for CaCl(2) and ...

Calculate `Lambda_(m)^(@)` for `CaCl_(2)` and `MgSO_(4)` from the data given in the following table:

Text Solution

Verified by Experts

Applying Kohlrausch law, `Lambda_(m(CaCl_(2)))^(@)=lambda_(Ca^(2+))^(@)+2lambda_(Cl^(-))^(@)`
`=119.0+2xx76.3="271.6 S.cm"^(2)."mol"^(-1)`
`therefore" "Lambda_(m(MgSO_(4)))^(@)=lambda_(Mg^(2+))^(@)+lambda_(SO_(4)^(2-))^(@)`
`=106.0+160="266 S.cm"^(2)."mol"^(-1)`.
