WebbTechnically, the pH scale measures the logarithmic concentration of hydrogen (H+) and hydroxide (OH-) ions, which make up water (H+ + OH- = H20). When both types of ions are in equal concentration, the pH is 7.0 or neutral. Below 7.0, the water is acidic (there are more hydrogen ions than hydroxide ions). how big is a uk army brigadeWebb10 apr. 2024 · In fact, the pH can reach a level of -3.6, which is highly acidic and dangerous to the environment.
