Respuesta :
The [OH-] of the solution increases as the pH rises. With an increase in [OH-], the reaction will shift to the left, according to Le C.hatelier's principle. Because the reaction has shifted to the reactant side, it is less soluble.
with increasing pH, the solubility of histone decreases.
Describing Le C.hatelier's principle:
Le C.hatelier's principle, also known as C.hatelier's principle, is a chemistry principle used to predict the effect of a change in conditions on chemical equilibria.
According to the information:
We have —NH₂.
As it dissolve or react with water, the —NH₂ will produce OH- in the given equation:
[tex]-\mathrm{NH}_2+\mathrm{H}_2 \mathrm{O} \rightleftharpoons-\mathrm{NH}_3^{+}+\mathrm{OH}^{-}[/tex]

I understand that the question you are looking for is:
Polymers are not very soluble in water, but their solubility increases if they have charged groups. (a) Casein, a milk protein, contains many -COO- groups on its side chains. How does the solubility of casein vary with pH? (b) Histones are proteins essential to the function of DNA. They are weakly basic due to the presence of side chains with -NH2 and =NH groups. How does the solubility of a histone vary with pH?
