NettetLe Chatelier's Principles Of The Generic Buffer System. As humans, we constantly need to regulate our bodily pH. This regulation process is called homeostasis, and is controlled by the hypothalamus and pituitary gland by a buffering system. A buffer solution is used to maintain the pH at a safe acidity. “A buffer solution is an aqueous ... NettetWhen a weak acid solution has common ions added by a salt, the equilibrium will shift by Le Chatelier's principle. ... Note that the buffer produced will not actually have a pH of 10. The concentrations are so high that we would need to compute activities from the ionic strengths and generate a corrected value of the Ka for ammonium ion.
