wt nqureld 10 Pailse the boiling point of 6. (12 pts) Consider each set of substances below. You should assume that all solutions are aqueous and that all solutes are completely dissolved at the indicated concentrations. For each set, circle the substance with the highest value of the indicated parameter (Pap. Tf, Tb, or osmotic pressure, ) and underline the solution with the lowest value of that parameter: (a) Pvap: 0.5 m sucrose (C12H22011) 1.0 m glucose (CoH1206) 1.5 m CasP2 1.5 m sucrose 1.0 m NaCl 1.5 m Li3PO4 1.0/NAI(CN); 2.0 m sucrose 1.0 m MgaN2 4.0 m sucrose 1.0NMg(NO3)2 1.0 m sucrose H20 1.5 m KCI 2.0Mglucose (b) Tb: (c) T (d) IT: 1.5 ACaCl2 2

Explanation / Answer

(a) 0.5 m sucrose

(b) 1 m Nacl because Higher the colligative property higher the Tb here Mg3N2 has highest colligative property and therefore highest Tb while Nacl lowest.

(c) 1.5 m KCl, because lesser the colligative property high will be Tf.

(d) 1M Al(CN) 3 because higher the colligative property more the osmotic pressure.

NOTE= collogatiive property= molesxNo of atoms x NA
