Carbon disulfide (cs2) has the unusual ability to dissolve several non metals as well as rubbers and resins. What are the boiling and freezing points of a solution consisting of 8.44g of phosphorus (p4) dissolved in 60.0g of cs2?
Boiling point point Boiling of water of sol Temperature Freezing point Freezing point of water of solution Like vapor pressure lowering, bo Quantifing boiling concentration of solute: on is proportional to the Kbrn or ATI ATH 2. the solution and K is the molal boiling point ee Cona ybtract the lower solvent 7b from the higher solution AT Tbosolution) Tb solvent), use it relates to mole fraction and, thus, to particles of eted by temperature Celsius per molal unit (Cum) and is Ab units of degrees water is 0.512 m, so AT for solvent (Table 13.6). for of glucose lutions is small. For example, if you dissolve 1.00 mol Molal Boiling Point Elevation and Freezing Point Depression Table 13.6 Constants of Several Solvents Boiling Point (°C)* Kb(CIm) Melting Point (C) Ki(clm Solvent 16.6 3.07 Acetic acid Benzene 80.1 2.53 5.5 Carbon disulfide 46.2 2.34 Carbon tetrachloride 76.5 5.03 23 Chloroform 61.7 470 3.63 63.5 Diethyl ether 34.5 119 2.02 116.2 Ethanol 78.5 1.22 Water 100.0 0.512 At 1 atm. Freezing Point Depression A solution freezes at a lower temperature than l. and this property also results from vapor lowering solute Why a freezes at a lower ure solution s molecules are left T. Only solvent vaporizes from behind, Similorlu
