Question:

Salicylic acid is similar in structure to aspirin. Shalmashi et al. have measured the data in Table 14.5.

(a) Find the value of α for salicylic acid in water that best correlates the data, assuming β = 0.

(b) Predict the solubility of the acid in ethanol.

(c) Plot log(xacid) versus 1000/T including correlated and measured values.

(d) Plot all the calculated versus experimental values. This is known as a parity plot.Table 14.5 Solubility of Salicylic Acid in Various Solvents. Compositions in Weight% 35 55 0.35 0.74 38.51
