Baking Soda to lower pH
"Tom L. La Bron" wrote in message
... Jan, Where have you heard this horse crap. Baking Soda when added to acidic water will raise the pH to a stabilized position and hold it there, but it certainly will not lower pH especially if you pH is already at the 8 level. Here's a good article on the chemistry of baking soda as a buffer, either raising or lowering ph http://www.mnwgs.org/articles/EmptykH.htm "But how can the bicarbonate act as a buffer to go the other way, lowering the pH if it is too high? In that case the bicarbonate ion would give up its hydrogen as an ion, thus adding acid, lowering pH, and becoming a carbonate ion (C03). HCO3 = C03 + H bicarbonate carbonate + H acid." |
