Bicarbonate bicarbonate – in conjunction with water, hydrogen ions, and carbon dioxide – forms this buffering system, which is maintained at the volatile equilibrium required to provide prompt resistance to pH changes in both the acidic and basic directions. This is especially important for protecting tissues of the central nervous system, where pH changes too far outside of the normal range in either direction could prove disastrous (see acidosis or alkalosis). Bicarbonate also serves much in the digestive system. It raises the internal pH of the stomach, after highly acidic digestive juices have finished in their digestion of food. Bicarbonate also
Acidic (band) cover the medical expenses of Deftones bass player Chi Cheng. ACIDIC is also involved with The Leukemia & Lymphoma Society, which helped drummer Matt Whitaker and his family during his battle with cancer. The band has supported that organization since 2008, playing at Light the Night walk-a-thon events and Man/Woman of the Year fundraisers. They worked with Charitybuzz in the spring of 2010, auctioning a guest slot in the band at one of their Whisky a Go Go concerts, which was won by a 17-year-old guitarist from Seattle. Critical raves continue to pour in for ACIDIC on CD and onstage.
