Talk:Buffer solution

From Wikipedia, the free encyclopedia

== removed section == I removed a section "Illustration of a buffer solution in action" because, to me at least, it was redundant with the following section, and the less well presented of the two. I hope that doesn't cause consternation. [[User:Olin|Olin]] 03:35, 9 March 2006 (UTC) I did some further cleanup, although the article still needs some help. [[User:Olin|Olin]] 04:10, 9 March 2006 (UTC) I have changed the equation of calculating the PH. The HA and A- was wrong way round. This is further confirmed through text book. I changed it back, per [[Henderson-Hasselbalch equation]]. I'll look it up when I get a chance.

IMHO, the formula stated is the correct one. --[[User:Beetstra|Dirk Beetstra]] 15:34, 6 June 2006 (UTC) ah ha....sorry, forgotten about the -log. thanks for reverting it back. == more buffers @ sigma-aldrich == Spam link! I do not see and kind of scientific value! http://en.wikipedia.org/wiki/User_talk:213.188.227.119 Best regards :Look, Scotty has beamed them to a more appropriate position, just as this remark of you! --[[User:Beetstra|Dirk Beetstra]] 16:21, 29 May 2006 (UTC) '''Bold text[[
