The solubility of an albumin is approximately (12 mathrm{~g} / mathrm{L}) at (left[left(mathrm{NH}_{4} ight)_{2} mathrm{SO}_{4} ight]=2.5 mathrm{M})

The solubility of an albumin is approximately \(12 \mathrm{~g} / \mathrm{L}\) at \(\left[\left(\mathrm{NH}_{4}\right)_{2} \mathrm{SO}_{4}\right]=2.5 \mathrm{M}\) and \(0.006 \mathrm{~g} / \mathrm{L}\) at \(\left[\left(\mathrm{NH}_{4}\right)_{2} \mathrm{SO}_{4}\right]=3.5 \mathrm{M}\). Determine value of constants \(\beta\) and K(salt) in Eq. (7-52) and then:

a. Predict albumin solubility at \(\left[\left(\mathrm{NH}_{4}\right)_{2} \mathrm{SO}_{4}\right]=3.0 \mathrm{M}\).

b. Predict albumin solubility at \(\left[\left(\mathrm{NH}_{4}\right)_{2} \mathrm{SO}_{4}\right]=3.75 \mathrm{M}\).

c. Predict albumin solubility at \(\left[\left(\mathrm{NH}_{4}\right)_{2} \mathrm{SO}_{4}\right]=2.4 \mathrm{M}\).

d. Predict albumin solubility at \(\left[\left(\mathrm{NH}_{4}\right)_{2} \mathrm{SO}_{4}\right]=2.0 \mathrm{M}\).

e. Which of these predictions is most likely reliable, and which is most likely seriously in error? Explain why.
