Question

Match the following aqueous solutions with the appropriate letter from the column on the right. 1. 0.21 m Bas 2. 0.24 m NH4CH3COO 3. 0.17 m Zn(CH3COO)2 4. 0.45 m Ethylene glycol(nonelectrolyte) A. Highest boiling point B. Second highest boiling point C. Third highest boiling point D. Lowest boiling point

Answer 1

There are some thermodynamic property of a solution which depends on the concentration of the solute in solution, but not on their chemical nature - there knopenty are called Colligative property. Some Common colligative property are (1 Relative towering of vapour pressure (11) Elevation of Boiling poin. Now Higher the Boiling point means, higher will be the elevation of boiling point. Now, for electroshtic Colution du value of colligative property such as Elevation of boiling point is greater then that of the non electrolyte. Because the electrolytes are dissociate to form ions, Consequently from the defination of colligative property it is clear that the value of Colligative finoperty for electrolytic solution win be greater than that of nun electrolyte. so (1) olim Bas lowcat boiling point (e) 0.240 wita 41000 Set omið tigla, fciling tooint @ 0.17m in Chicoulz - 5 Highest boiling point (470.45 m Flylene glycol non electrolyta B ailing bow 30d highest Bc.orim Basazions - 0.92m [6] 2.0.29m wila CH₃Coo z ions 0.48 m A 3. oltm zn Cert(o) - sions - 0.5m [C] 0-45 m Ellylzue giyeol 1.0.16 m Ca (NUK) -> 3ions (0-1683 )-(48 m) B] 0.17m Cabr - sions > (0-1783 ) = (0.51 m) A 3 0.27 m kt rioos - 0.54 m.
