depends on the mole ( concentration ), usually 0 or 1
There are many acids that have a pH lower than 4.6. Hydrochloric acid for example has a pH of less than 2.
Are you perhaps referring to hydrochloric acid? If so, it is one of the strongist acids, with a pH of 2. However, there are stronger acids, such as carborane acid and fluorosulphuric acid.

Dilute hydrochloric acid typically has a pH around 1 to 2.
The pH of hydrochloric acid has a pH of 2.
There are no acids that have a pH of exactly 1 because pure water has a pH of 7 at 25°C. Acids with a pH close to 1 include hydrochloric acid (HCl) and sulfuric acid (H2SO4), which are strong acids that can result in low pH values when dissolved in water.
Hydrochloric acid (pH 1), Blood (pH 7.4), Ammonia solution (pH 11). The order from lowest to highest pH is: Hydrochloric acid (pH 1) < Blood (pH 7.4) < Ammonia solution (pH 11).
Strong acids are found at the lowest end of the pH scale, typically between 0 and 1. Examples of strong acids include hydrochloric acid, sulfuric acid, and nitric acid, which can fully dissociate in water to release H+ ions.
Hydrochloric acid pH is anywhere from 7 (neutral) to 0 (extremely acidic) on the conventional pH scale which runs from 0 to 14, depending on the concentration in water. It is among the strongest acids known. A concentration of 0.1 mol per litre has a pH of 1. The pH of commercial hydrochloric acid sold as "spirits of salt" has a theoretical pH less than zero and is highly corrosive.
Honeybee venom is a weak acid, so most other acids are stronger acids.
It decreases the pH of the stomah juices to around pH 4. This allows the zymogen pepsinogen to be cleaved into the enzym pepsin which breaks down proteins into amino acids.
The pH of acids ranges between 1 to 6. The one with pH 1 is the most concentrated. The pH is a measure of the concentration of H+ ions in a solution.
