PH 75 is the most acid.
The pH of vinegar depends upon how much acid is present, but most commercial distilled white vinegars contain 5% acetic acid and have a pH of about 2.4.
Muratic acid (Hydrogen Chloride) at a 10% concentration has a PH of -.5. This is the concentration that is available for most houshold uses.
what is the ph of tannic acid
stomach acid has a lower ph, therefore a stronger acid
PH 75 is the most acid.
Acids generally have a pH ranging from 1 - 6. pH 1 being the most acidic, and pH 6 being the least acidic. eg, hydrochloric acid, nitric aicd, sulfuric acid has a pH of 1. Ethanoic acid has a pH of 3.

The base pH of acid rain is low, yes. Usually around 2.5 to 5.5 are the most acidic.

20.6 This can't be correct ... the pH scale goes from 0 (most acid) to 14 (most basic). pH 7 is neutral.
Whether something is acid or base the strength of that solution is measured by the pH scale. 0 (zero) is the most acid and 14 is the most base. distilled water measures 7 and is completely neutral. Ammonia is an example of a base and is usually measured at a pH of 11.6. So the answer to your question is that an acid has a positive pH. There is no such thing as a negative pH.

The most effective way to maintain a stable pH is by the use of a buffer. These are solutions of a weak acid or a weak base, and the conjugate base or acid, adjusted to the desired pH.
A pH of 1 is most acidic. The acid in your stomach is about a 2 and it is strong enough to burn a hole in a rug.
The pH of hydrochloric acid has a pH of 2.
