HNO3
The pKa value of H3O in aqueous solution is approximately -1.74.
Phosphorus trichloride (PCl3) is a covalent compound and does not have a pH level. pH is a measure of the acidity or alkalinity of a solution and is applicable to aqueous solutions. PCl3 is a liquid compound and not soluble in water, so it does not have a pH value.
Substances don't have a uniform pH. It depends on the concentration. That said, I would expect TNT to be neutral, or nearly so.
pKa is measured for acid in aqueous solution while hexane is an organic liquid immiscible with water so pKa value is meaning less for hexane.
The pH of a 0.1 molar aqueous solution of HCl would be 1. This is because HCl is a strong acid that completely dissociates in water to produce H+ ions, resulting in a high concentration of H+ ions in solution, leading to a low pH value.
The pKa value of H3O in aqueous solution is approximately -1.74.
A 1.0 M aqueous solution has a pH of 11.6
pH is the negative log of the activity of the hydrogen ion in an aqueous solution. A powder is not a solution.

Many industrial and biological processes occur at a specified value of pH.

Hydrogen chloride is an acid and its acidity depends on the concentration of the solution. For example, a 0.1M solution of HCl has a pH value of 2.0
Nitrogen gas does not have a pH value because it is not an aqueous solution and does not produce ions in water to measure pH. pH is a measure of the concentration of hydrogen ions in a solution, which is not applicable to nitrogen gas.
pKa is measured for acid in aqueous solution while hexane is an organic liquid immiscible with water so pKa value is meaning less for hexane.
A strong acid, such as hydrochloric acid (HCl), has a pH of 1 and completely ionizes in aqueous solution, meaning all molecules dissociate into their constituent ions. This leads to a high concentration of hydrogen ions (H+) in the solution, resulting in the low pH value.
The pH of a 0.1 molar aqueous solution of HCl would be 1. This is because HCl is a strong acid that completely dissociates in water to produce H+ ions, resulting in a high concentration of H+ ions in solution, leading to a low pH value.
