Values below 7 indicate … 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). fitting hinges to cabinet doorsWebpH is a measure of hydrogen ion concentration, which is measured as a negative logarithm. In other words, acids produce hydrogen ions and alkalis produce hydroxyl ions, so pH is the power of a solution to yield hydrogen ions [H+]. The pH scale ranges from 0 to 14 and indicates how acidic or basic a substance is. A pH of 7 is neutral. fitting hive mini
