Heartburn indigestion is caused by acid from the stomach irritating the upper digestive . tract.. For . those who suffer regularly, treatments are available to . antacids. Acid indigestion/heartburn. Acid indigestion (discomfort in stomach) and heartburn (acid rising into . oesaphagus. ) are conditions which arise when excess hydrochloric acid is produced by the gastric glands in the walls of the stomach. The acid, which creates an acidic environment of pH 0.3 to 1.2 is needed to. Unit 14 Buffers and Antacids 140 Frequent use of antacids may warrant the use of non-sodium containing products. Back Tritrations. A back titration is where you titrate what has not reacted rathe (maybe… but Probably not. We’re all going to fail).. . By: Madeline Doolin, Bailey Hiles & Adrian Burrus. The Problems. -The stomach maintains a pH of 1-2 due to the secretion of hydrochloric acid by parietal cells in the stomach wall. The extreme acidic environment allows all enzymes to function properly, digesting food and eliminating bacteria.. D4 . pH regulation of . the stomach. Understand that antacids can be used to reduce the amount of excess acid in the . stomach.. Understand that the action of antacids is . non-specific.
