Low: acidic.
Tums react with acids from the stomach.
The average pH level of humans' stomach acids are 1.2-3.6
Acids are substances that can donate protons, while antacids are substances that neutralize acids in the stomach to relieve heartburn or indigestion. Acids can be harmful if ingested in excess, while antacids provide relief by balancing stomach pH levels.
The lower a pH level is, the more acidic it is. The acid in your stomach, hydrochloric, is very acidic, and can even burn through some items.
2 pH is the answer
Stomach acid is not very strong compared to chemical acids available on the market. One thing that has about the same pH as stomach acid is lemon juice.
the pH of stomach acid would be below 7, but the pH of oven cleaner would be above 7.
The lining of your stomach is replaced every three days due to the low pH of your stomach acids.
The stomach is covered in mucus to protect it from the strong acids used to digest proteins. The duodenum (the very first section of the small intestine) does not have such mucus to protect itself. The pH change is crucial to make sure that the duodenum is not harmed by the strong acids from the stomach.
acid pH < 7base pH > 7
When your stomach is upset, it is usually due to an increase in the acidity (decrease in pH) of your stomach. Since your stomach is thus more acidic than what is usual, bases such as Alka-Seltzer and Pepto-Bismol help to neutralize some of the stomach acid that's causing the problems, thus bringing the user some relief. Bases have a higher pH than acids, and thus, when mixed with acids, depending on the strength of the base, will neutralize it to some degree.
Most of the body has a pH that is slightly basic. The only place in the body that is acidic would be in the stomach, where the stomach acid has a pH of 1.5 to 3.5, which is very acidic.
