Find out the molar conductivity of an aqueous solution of BaCl_(2) at infinite dilution when ionic conductances of Ba^(2+) and Cl^(-) ion are 127.30 S cm^(2)mol^(-1) and 76.34 S cm^(2)mol^(-1) respectively.

Answer»


SOLUTION :`wedge_(m)^(@)(BaCl_(2))=lamda_(BA^(2+))^(@)+2lamda_(CL^(-))^(@)=127.30+2(76.34)" S "cm^(2)mol^(-1)=279.99" S "cm^(2)mol^(-1)`
