Sodium hydrogen carbonate

December 11, 2006

Sodium hydrogen carbonate (sodium bicarbonate, NaHCO3) is a time-honored remedy for acid indigestion. It gives off CO2 when it is heated, which makes cakes and cookies rise during baking. It can also remove ink buildup from printing presses, and it is an environmentally friendly alternative to sandblasting for removing graffiti from buildings.
