At infiinite dilution, the aqueous solution of BaCl_(2). M olar conductivity of Ba^(2+) and Cl^(-) ions are =127.32 S cm^(2) /mol and 76.34S cm^(2)/mol respectively what is ^^_(m)^(@)for BaCl_(2) at same dilution?

Answer»

`280Scm^(2)"MOL"^(-1)`
`330.98S CM^(2)"mol"^(-1)`
`90.98S cm^(2)"mol"^(-1)`
`203.6S cm^(2) "mol"^(-1)`

SOLUTION :`^^_(m)^(oo)=^^_(BA^(2+))^(oo)+2lambda_(Cl^(-))^(oo)`
`=127.32+2xx76.34`
`=280S cm^(2) "mol"^(-1)`
