The pH scale is used to rank solutions in terms of how acidic or how basic they are. It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. These ion concentrations are equal in pure water, which has a pH of 7. This pH value of 7 is important because it indicates a neutral solution.
WebRegarding intradermal testing, the parameter states: “Both erythema and wheal diameters should be measured and recorded. Erythema can be measured as reliably as wheal … The pH scale goes from one to fourteen. The number 7 is about halfway down the scale, and a pH of 7 indicates a neutral solution. Neutral solutions include either no acid or no base, or equal levels of both. A solution with a pH less than 7 is acidic, whereas one with a pH more than 7 is basic. Visa mer In lead-acid batteries, sulphuric acid is employed as an electrolyte. Because of the interaction with sulphuric acid, lead sulphate forms on both electrodes during the discharge of lead-acid batteries.
