1.	The molar mass of the solute sodium hydrdoxide obtained from the measurement of the osmotic pressure of its aqueous solution at `27^(@)C` is `25 g mol^(-1)`. Therefore its ionization percentage in this solution isA. 75B. 60C. 80D. 70
Answer» Correct Answer - B In case of ionisation of binary electrolyte Abnormal molecular mass `=(M_("normal"))/(1+alpha)` Abnormal molecular mass = 40 So, `25=(40)/(1+alpha)rArr alpha =0.6` Ionisation percemntage `= 0.6xx100=60%`.
