WebHydrogen ion concentration or pH plays a significant role in HMs bioremediation by microorganisms since it affects the microbial biosorption (Banerjee et al., 2024 ). The pH affects the enzymatic activity, cell-surface charge of microbes, and hydration as well as mobility of metal ions. WebIn order to deal with these large numbers more easily, scientists use a logarithmic scale, the pH scale. Each one-unit change in the pH scale corresponds to a ten-fold change in hydrogen ion concentration. The pH scale is theoretically open-ended but most pH values are in the range from 0 to 14. Pure water is neutral. When an acid is dissolved in water, the pH will be less than 7 (25 °C). When a base, or specifically an alkali, is dissolved in water, the pH will be greater than 7. A solution of a strong acid, such as hydrochloric acid, at concentration 1 mol dm has a pH of 0. A solution of a strong alkali, such as sodium hydroxide, at concentration 1 mol dm , has a pH of 14.
