Antacids are bases used to neutralize the acid that causes heartburn. Despite the many commercial brand‚ almost all antacids act on excess stomach acid by neutralizing it with weak bases. The most common of these bases are hydroxides‚ carbonates‚ or bicarbonates. The following table contains a list of the active ingredients found in several common commercial antacids‚ and the reactions by which these antacids neutralize the HCl in stomach acid.

PHOTOSYNTHESIS Theory: Leaf discs float normally. When the air spaces are infiltrated with the solution the overall density of the leaf disc increases and the disc sinks. The infiltration solution includes a small amount of sodium bicarbonate. The bicarbonate ions serve as the carbon source for photosynthesis. As photosynthesis proceeds oxygen is released into the interior of the leaf which changes the buoyancy – causing the discs to rise. Since cellular respiration is taking place at the same
