A 1.2% solution (w/v) of NaCl is isotonic with 7.2% solution(w/v) of glucose. Calculate degree of ionization and Van't Hoff factor of NaCl.

Explanation

`{:("NaCl",,"glucose"),(pi_((NaCl)),= ,pi_("glucose")),(iC_(1)RT,=,C_(2)RT),(iC_(1),=,C_(2)),(i((1.2//58.5)/(V)),=,(7.2//180)/(V)):}`
`i=(7.2xx68.5)/(1.2xx180)=1.95`.
