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?
