Of the following four aqueous solutions, total number of those solutions whose freezing point is lower than that of 0.10 M C2H5OH is __________ (Integer answer)

(i) 0.10 M Ba3(PO4)2

(ii) 0.10 M Na2SO4

(iii) 0.10 M KCl

(iv) 0.10 M Li3PO4

Step-by-Step Verified Solution

As 0.1 M C2H5OH is non-dissociative and rest all salt given are electrolyte so in each case effective molarity > 0.1 so each will have lower freezing point.
