The addition of a small amount of a salt, such as (NH4)2SO4, to a solution containing a charged protein increases the solubility of the protein in water. This observation is called the salting-in effect. However, the addition of large amounts of salt can decrease the solubility of the protein to such an extent that the protein precipitates from solution. This observation is called the salting-out effect and is used widely by biochemists to isolate and purify proteins. Consider the equilibrium PXν(s) ⇋ Pν+(aq) + ν X−(aq), where Pν+ is a polycationic protein of charge ν+ and X− is its counterion. Use Le Chatelier’s principle and the physical principles behind the Debye–Hückel theory to provide a molecular interpretation for the salting-in and salting-out effects.

A friend of yours who is taking a biochemistry class saysthat salting out works because the waters of hydration thatsurround the protein prefer to surround the electrolyte asthe electrolyte is added; therefore, the protein’s hydrationshell is stripped away, leading to protein precipitation. Anotherfriend of yours in the same biochemistry class saysthat salting out works because the incoming ions adsorbtightly to the protein, making ion pairs on the protein surface,which end up giving the protein a zero net charge inwater and therefore leading to precipitation. Discuss thesetwo hypotheses. What kind of measurements would youneed to make to distinguish between these two hypotheses?
A student obtained a solid product in laboratory synthesis. To verify the identity of the solid, she measured the milting point and found that the material melted over a 12°C range. After it had cooled, she measured the melting point of the same sample again and found that this time the solid HUD a sharp melting point at the temperature that is characteristic of the desired product Why were the two melting points different? What was responsible for the change in the melting point?
