14. Tris is the trivial name for tris(hydroxymethyl)aminomethane and forms an effective buffer with its hydrochloride salt in the pH range 7-10.
15. As we discuss later in the text, some small concentration of buffer is needed in order to maintain a stable pH. All salts are very weak acids and bases, and the pH of water containing different salts is difficult to predict, unstable to small changes in temperature and atmospheric concentration of carbon dioxide.
