Q:

What is the pH of hydrochloric acid?

A:

The pH of hydrochloric acid is 0, which means that it has the highest degree of acidity on the pH scale. Hydrochloric acid is a clear and highly corrosive solution of hydrogen chloride in water. In addition to its many industrial uses, hydrochloric acid is also found naturally in the digestive system in the form of gastric acid.

The pH scale ranges between 0 and 14. Neutral pH is represented by 7, which would be that of distilled water. Those pH levels above 7 and up to 14 are the readings that would be obtained from those substances termed bases. A pH reading of 14 represents the highest degree of alkalinity, a term used to describe the relative strength of a base.
