I was looking for the answer to this too, and found that Gastrin (a hormone of the stomach) stimulates hydrochloric acid to be released to maintain the appropriate pH level. Are you in the same nutriton class as me? haha cause this is a quiz question for mine.
Gastrin
In our stomach the acidity level (pH) is between 1-2.
pH = ZERO - very strong acid
all acidic substances with a PH below 7< turn the Universal indicator red due to their acidity.
You can use pH in any sentence that requires you to compare the acidity of two or more substances.
Scientists carry out pH tests on a whole range of substances to ascetain their acidity or alkalinity
Gastric juice consists of hydrochloric acid, a strong acid along with many weak acids. Free acidity is a measure of acidity of hydrochloric acid alone but total acidity is a measure of combined acidity due to hydrochloric acid and many weak acids (organic acids and proteins).
Excessive acidity.
Hydrochloric acid (HCl)
The addition of hydrochloric acid feel hyper acidity which reduces the sleepiness.
to prevent acidity we must take bases such as antacid or alkaline solution as it neutralises the affect of excessive acids.
acidosis
These substances are called pH indicators.

Acidity and alkalinity of substances.
