Best answer
(i) `K_(2)C_(2)O_(4)to2K^(+)+C_(2)O_(4)^(2-)`
`:." "^^_(MK_(2)C_(2)O_(4))^(oo)=2^^_(MK^(+))^(oo)+^^_(MC_(2)O_(4)^(2-))^(oo)` ltbr `2xx50.1+148.2`
`=248."सीमेंस सेमी"^(2)" मोल"^(-1)`
अब `^^_(eq.K_(2)C_(2)O_(4))^(oo)=^^_(eq.K^(+))^(oo)+(1)/(2)^^_(eq.C_(2)O_(4)^(2-))^(oo)`
`=50.1+(1)/(2)xx148.2`
`=124.2" सीमेंस सेमी"^(2)" तुल्यांक"^(-1)`
(ii) `KNaC_(2)O_(4)toK^(+)+Na^(+)+C_(2)O_(4)^(2-)`
`:." "^^_(MKNaC_(2)O_(4))^(oo)=^^_(MK^(+))^(oo)+^^_(MNA^(+))^(oo)+^^_(MC_(2)O_(4)^(2-)`
`=50.1+73.5+148.2`
`=271.8" सीमेंस सेमी"^(2)" मोल"^(-1)`
अब, `^^_(eq.KNaC_(2)O_(4))^(oo)=(1)/(2)[^^_(eq.K^(+))^(oo)+^^_(eq.Na^(+))^(oo)+^^_(eq.C_(2)O_(4)^(2-))^(oo)]`
`=(1)/(2)[50.1+73.5+148.2]`
`=135.9" सीमेंस सेमी"^(2)"तुल्यांक"^(-1)`
