Molar conductances of BaCl_(2), H_(2)SO_(4) and HCl at infinite dilution are andX_(1),X_(2), and X_(3) respectively. Molar conductance of BaSO_(4) at infinte dilution is

Answer»

`(500x)/((x_1 + x_2 - 2x_3))`
`(10^(6) X^2)/((x_1 + x_2 - 2x_3)^(3))`
`(2.5 xx 10^(5) x^(2))/((x_1 + x_2 - x_3)^(2))`
`(0.25x^(2))/( (x _1 + x_2 - x_3)^(2))`

Solution :`BaSO_4 = (BaCl_2 + H_2SO_4 -2HCL) , ^^_(BaSO_4) = (2x_1 + 2x_(2) - 2x_(3)) = 2 (x_1 + x_2 - x_(3))`
` S=M =(K xx 1000)/(^^_M) = ( x xx 1000)/(2(x_1 + x_2 - x_3)) , K_(SP)(BaSO_4) = S^(2) = (x^(2) xx (500)^(2))/((x_1 + x_2 - x_3)^(2)) , K_(sp) = (x^(2) xx 2.5 xx 10^(5))/((x_1 + x_2 - x_3)^(2))`
