A `1.17%` solution of `NaCl` is isotonic with `7.2%` solution of glucose. Calculate the Van't Hoff factor of `NaCl`.

Text Solution

Verified by Experts

For isotonic solution, osomotic pressure should be same.
`:. pi_(NaCl)=pi_("glucose")`
`iC_(1)RT=C_(2)RT`
`iC_(1)=C_(2)`
i`((1.17//58.5)/V) = (7.2//180)V rArr (7.2xx58.5)/(1.17 xx 180) =2`
