This is an extremely acid solution; pH under 1.
The pH value of the solution depends on the strength of the acid, in other words, acid concentration.
Its pH is 3
The pH of hydrochloric acid has a pH of 2.
There is no substance with a pH of 25. But the lower the pH, the more acidic a solution.

Well that depends on how much acid there is and depends on what the pH of the solution is.
The pH of hydrochloric acid has a pH of 2.
There is no substance with a pH of 25. But the lower the pH, the more acidic a solution.
HCl is a very strong acid: dilute solution (eg. 3.65 g/L) has pH of 1.0 , or when concentration is 3.65 mg/L then pH = 4.0.
what is the Ph of a solution containing 5mg/L of hydrochloric acid?
pH = ZERO - very strong acid
There is no definite pH of hydrochloric acid or any other substance. pH is a measure of the concentration of hydrogen ions in a solution which depends on both how strong an acid or base is and how concentrated it is (how much is dissolved in a given volume of water). Because hydrochloric acid is a strong acid the pH can be calculated as the negative logarithm (base 10) of its molar concentration up to a pH of 7.
This depends on the concentration; for example, the pH of a 10% solution is -0.5, but that of a 30% solution is -1.0.There are two points to make about this question. First, the pH of any acid or any substance depends upon its concentration in water, usually given by chemists in the form of moles per liter. Secondly, there is no hydrocolic acid, you are probably thinking of hydrochloric acid, which is quite strong as acids go, and in a high concentration could have a pH of 1.
One possibility is a 10% solution of hydrochloric acid.
