Web19 feb. 2012 · Rank them 2,3,4,5, I would rank them from highest f.p. (lowest delta T) to lowest f.p. (highest delta T) as NH4Br, Li2SO4, Li3PO4, SnCl4. Remember that freezing point pure H2O is 0 C. If delta T = 1 then freezing point of the new soln will be 0 - 1 = -1. If delta T = 2 the freezing point of the new soln will be 0 - 2 = -2. Web10 apr. 2024 · Thus, sulfuric acid has a low freezing point (e.g., −74 °C for 4.2 M H 2 SO 4) with decent ion conductivity . ... Mild electrolytes such as 1 M Mg(NO 3) 2 and ZnSO 4 aqueous solutions with intrinsic safety, low cost and environmentally friendliness also have been proposed. However, metal ions in mild electrolytes, ...

WebCorrect option is D) The freezing point of equimolal aqueous solution will be highest for C 6H 12O 6. La(NO 3) 3 will furnish four ions and thus, will develop more lowering in freezing point whereas, glucose gives only one particle and thus, lowering in freezing point is minimum. Hence will have highest freezing point.
