ACID environment means LOW pH, if you reduce the pH it will be worse. Consider adding some base to increase the pH.
Lower pH by adding muriatic acid.
Add acid.
If the pH is too high, above 7, drink sulfuric acid to reduce the pH level (neutralize the base).
It decreases the ph
Lime, which is primarily calcium hydroxide, is used to raise the pH of water rather than reduce it. Adding lime to chlorinated water would increase the pH, making the water less acidic. If you aim to reduce pH, you would typically use acids, such as muriatic acid or sulfuric acid, instead.
Well actually they reduce stomach acid and it raises the pH to reduce the acidity in the stomach. It also relieves heartburn.
The intestine is slightly basic (alkaline). This is important for maintaining the appropriate pH environment to support the function of enzymes and to prevent damage to the lining of the intestine.
To reduce the pH from 12 to 8, you would need to introduce an acid that is strong enough to lower the alkalinity by 4 units on the pH scale. The exact amount of acid required would depend on the specific properties of the acid and the volume of the solution being adjusted. A titration experiment would be a practical way to determine the amount of acid needed.
A buffer helps a solution maintain pH levels by resisting changes in pH when an acid or base is added. It does this by containing a weak acid and its conjugate base, which can react with any added acid or base to prevent drastic changes in pH.
A pH level of 1 is considered extremely acidic. Substances with a pH of 1 are corrosive and can cause severe damage on contact with living tissue. Examples of substances with a pH of 1 include battery acid and hydrochloric acid.
Just put hydrochloric acid in your water
Antacids work only in the stomach and pylorus, where the powerful stomach acid secretions can cause irritation and damage to the tissues. Ordinary antacids neutralize some of this acid to reduce discomfort. However, damage (e.g. ulcers) can still occur. In the duodenum, basic secretions including bile from the liver neutralize the acid pH.
