So, let's suppose we begin to add our sodium chloride molecules. As soon as we add the sodium chloride molecules, the ionic bond holding the sodium chloride will break. And what happens is, when we dissociate the two atoms, they will form ions. So we're going to have a bunch of positively charged sodium ions and a bunch of negatively charged chloride ions floating around in our aqueous solution. Now, because we don't increase or decrease the amount of water molecules present inside our mixture, what that means is the number of hydrogen bonds that are available to interact with the hydrophilic amino acids of the protein will decrease. And if we decrease the amount of stabilizing hydrogen bonds interacting with our protein, that will destabilize the structure of these individual proteins.
