http://www.protocol-online.org/biology-forums/posts/40008.html WitrynaHCl/KCl buffer is going to be fairly small since you can manipulate the ionization of HCl over only a relatively narrow range, over towards the "completely" ionized end of the range. However, the principle is the same. Sorry for the mostly untrimmed quoted text. It seemed sensible to leave it in place. - Shankar Marvin 15 years ago ...
WitrynaThe quick answer is that tris is a basic buffer, whereas tris HCl is the acidic buffer. Keep in mind, buffers are used to resist changes to pH. Even small concentrations of a strong acid or base, without a buffer, could significantly change environmental pH. Therefore, a reason for choosing between tris HCl or tris base may also depend on what ...
