Expert Solution & Answer

Answer to Problem 9.89UTC

Solution:

(a) 1

(b) 2

(c) 1

Explanation of Solution

There are different type of interaction between polar-polar, nonpolar-nonpolar and nonpolar-polar species. Therefore, one must ensure that the solute and solvent are well defined.

The solute is always in smaller amount than the solvent. Image (1) states an uniform mixture of species, whereas image (2) shows two phase, no mixture.

For any given mixture, there must be then either a polar-polar or a nonpolar-nonpolar solute/solvent system.

Image (2) shows the only combination possible, a nonpolar-polar mixture.

Conclusion

Always ensure to identify the solute, solvent and the type of interaction between them.

Experiment: Each team will be provided with 5g of a mixture of acetanilide and salicylic acid. You will divide it into three 1.5 g portions in separate 125 mL Erlenmeyer flasks savıng some for melting point analysis. Dissolve the mixture in each flask in ~60mL of DI water by heating to boiling on a hotplate. Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below. Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization. Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C Sample C-Cool the third sample in an ice-bath to 0-2 °C Results: weight after recrystalization and melting point temp. A=0.624g,102-115° B=0.765g, 80-105° C=1.135g, 77-108 What is the percent yield of A,B, and C.
