• The depression in freezing point is given by ΔTF = KF · b · i,
where i depend upon the number of ions produced by the solute in a solution.
• The higher the value of i obtained, the higher the depression freezing point .
,
• CaCl2 (aq) → Ca2+ (aq) + 2Cl– (aq).....(3 ions)
,
• and NaCl Na+ and Cl– ions →...............(2 ions )
,
• Sugar/sucrose doesnt dissociate
,
• Thus CaCl2 will have similar freezing point as water . Option B
,
•
