wedge^(@)._(m) for CaCl_(2) and MgSO_(4) from the given data. lambda_(Ca^(2+))^(@)=119.0S cm^(2)mol^(-1) ltbr. lambda_(Cl^(c-))^(@)=76.3S cm^(2)mol^(-1) lambda_(Mg^(2+))^(@)=106.0S cm^(2)mol^(-1) lambda_(SO_(4)^(2-))^(@)=160.0 cm^(2)mol^(-1)

Answer»

Solution :`Lambda_(m(CaCl_(2)))^(@)=Lambda_(m(CA^(2+)))^(@)+2Lambda_(m(Cl^(-)))^(@)`
`=119+(2xx76.3)="271.6 S CM"^(2)" MOL"^(-1)`
`Lambda_(m(MgSO_(4)))^(@)=Lambda_(m(Mg^(2+)))^(@)+2Lambda_(m(SO_(4)^(2-)))^(@)`
`=106+160="266 S cm"^(2)" mol"^(-1)`
