fredrik Posted February 26, 2007 Share Posted February 26, 2007 And beer. The dominating malt buffers are various phosphates, which then interact with water carbonates and organic acids produced during fermentation. Therefore most beers have a fairly similar pH. Wine is more acidic partly because the buffering power in wine must is lower and second due to more organic acids in the first place. /Fredrik Link to comment Share on other sites More sharing options...
John Cuthber Posted February 26, 2007 Share Posted February 26, 2007 Offhand, I can't think of any biological system that isn't buffered, possibly stomach contents which are strongly acid. Tears, blood, milk etc are all buffered. Link to comment Share on other sites More sharing options...
Borek Posted February 26, 2007 Share Posted February 26, 2007 Stomach? Strong acid solution behaves as buffer as well - pH doesn't change much when you add small amounts of acids/bases. See buffer and buffer capacity discussion. Link to comment Share on other sites More sharing options...
