1.

Calculate Lambda_(HOAc)^(@) using appropriate molar conductances of the electrolytes listed above at infinite dilution in water at 25^@C.

Answer»

`517.2`
`552.7`
`390.7`
`217.5`

SOLUTION :`(Lambda_(oo))_(HOAC) = [(Lambda^@)_(HCl) + (Lambda^@)_(NAOAC)] - (Lambda^@)_(NACL)`
`(426.2 + 91) - (126.5) = 390.7`.
