- Explain why the partition coefficient of salicylic acid is different when a solution of 0.01 M HCl in water (pH ~ 2.0) is used as the aqueous layer compared to when just water (pH ~ 7) is used.state 2 advantages of transitional theory over collision theoryDistinguish between TSS and TDS to understand why one is a physical parameter and the other is a chemical parameter.
- Derive an expression for the temperature dependence of Kc for a general gas-phase reaction.Solute S has a partition co-efficient of 3.0 between water (Phase 1) and Chloroform (Phase 2). (a) Calculate the concentration of S in chloroform if [S(aq)] is 0.015 M. (b) If the volume of water is 75.0 mL and the volume of chloroform is 15.0 mL, find the quotient (mol S in chloroform)/(mol S in water).Ethyl heptanoate (EH), a food aroma compound, was added to water and allowed to come to equilibrium with a known volume of air and results showed that its partition coefficient, [EHair]/[EHwater] is equal to 1.8 x 10-2. In the same experiment with oil in place of water, its partition coefficient, [EHair]/[EHoil] is found to be lower at 6.0 x 10-6. Account for the difference between the two values.
