WebTechnically, 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). WebThe overall concentration of hydrogen ions is inversely related to its pH and can be measured on the pH scale (Figure 1). Therefore, the more hydrogen ions present, the lower the pH; conversely, the fewer hydrogen ions, the higher the pH. … The environment in your stomach is highly acidic (pH = 1 to 2). Is H+ high or low pH?

WebAcids release H+ ions (protons) when dissolved in water, Alkali release OH- ions instead. Chemical Reactions of Acids. If you don’t know this, it’s quite sad.
