the digestive system produces a hydrochloric acid medium for the action of pepsin without which it would be impossible to digest proteins. this hydrochloric acid emission causes the pH of the stomach.
The secretion that causes the increase in pH when chyme moves from the stomach into the small intestine is bicarbonate, which is released by the pancreas. Bicarbonate helps to neutralize the acidic chyme from the stomach, creating a more favorable environment for digestion to continue in the small intestine.
Your stomach acid has a pH of 1.5 to 3.5
pH of stomach juice is between 1 and 2.
Stomach pH at digestion is 2.
The pH of the stomach is typically around 1.5-3.5, which is very acidic. This acidity is necessary for the digestion of food and to kill bacteria that may be present in the stomach.
The pH of your stomach changes depending on what you are eating. If you are digesting a fat the solution can increase.
It is usually not too high of acidity that causes acid reflux. Acid reflux is a product of a faulty cardiac sphincter, which allows the highly acidic chyme to flow back into the esophagus. Your esophagus is not protected from the acid like your stomach is with the stomach lining of mucus. The pH range of stomach acid is about 1.5-2, which is strong enough to dissolve iron nails.
It means that the stomach is very acidic.
2 pH is the answer
Pepsin is therefore acidic since the pH in the stomach is 2
The normal pH of the stomach is about 2-3 and is caused by a high concentration of HCl secreted by the parietal cells of the stomach.
The pH of stomach acid typically ranges from 1.5 to 3.5. After taking an antacid, which is a base that neutralizes stomach acid, the pH of the stomach acid is expected to increase, becoming less acidic and moving closer to a neutral pH of 7.
