(ii) 5 M CaCl2
(iii) 3 M Na3PO4
(iv) 2 M Ca3(PO4)2

Prashant Kotian · Accepted Answer

Correct answer: D. fT im   Higher value of im, lower the freezing point. (i) im 2 2 4    (ii) im = 5 3 15   (iii) im 3 4 12    (iv) im = 2 5 10   यश TG~ @bohring_bot AITS-FT-VII-PCM(Sol.)-JEE(Main)/2024 FIITJEE Ltd., FIITJEE House, 29-A, Kalu Sarai, Sarvapriya Vihar, New Delhi -110016, Ph 46106000, 26569493, Fax 26513942 website: www.fiitjee.com 10
