What Is the PH of HCl?

According to the Hyperphysics Web page of Georgia State University, concentrated HCl has a pH of 0. The pH of HCl is highly dependent upon the concentration of HCl in water. The less concentrated the HCl solution, the higher its pH level.

The pH level of a solution is determined by the concentration of hydrogen it contains. The lower a pH level, the more acidic the material.

HCl is located within the body and helps food digestion. HCl is also used in several industrial processes, such as making plastic or processing leather. It is additionally used in cleaning solutions. The pH of most HCl solutions is acidic enough to damage skin.
