A storage battery contains a solution of `H_(2)SO_(4) 38%` by weight. What will be the Van't Hoff factor if the `Delta"T"_("f(experiment)")` in 29.08. `["Given K"_("f")=1.86 " mol"^(-1)" Kg"]`

Text Solution

Verified by Experts

The correct Answer is:
i=2.5
`"H"_(2)"SO"_(4)-"B and H"_(2)"O"-"A"`
`Delta"T"_("f")="i"xx"K"_("f")("W"_("B")xx1000)/("m"_("B")xx"W"_("A")"(gm)")`
`29.08="i"xx(1.86xx38xx1000)/(38xx62)`
`"I"=2.5`
