Ph scale what value is assigned to neutral

WebBases on the pH scale If a substance is 7 on the pH scale, it is neutral, meaning it is neither an acid nor a base (water, for example, is neutral). When a substance is higher than a 7 on a pH scale, the substance is basic. A weak base is assigned a pH between 8 and 10, while a strong base is assigned a pH between 11 and 14. WebMay 20, 2024 · If pH = 7, then the solution is neutral. If pH > 7, then the solution is basic. This is known as the \(pH\) scale. The pH scale is the range of value s from 0 to 14 that describes the acidity or basicity of a solution. You can use \(pH\) to make a quick determination whether a given aqueous solution is acidic, basic, or neutral.
