WebbReading the pH scale. 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. Webb10 maj 2024 · A pH meter measures the acidity or alkalinity of a solution. Acidic solutions have positively charged hydrogen ions, and alkaline solutions have negatively charged hydroxide ions. pH stands for the power of hydrogen, and it is calculated based on the number of hydrogen ions in a liquid.
