WebMay 6, 2024 · pH describes how acidic or basic an aqueous solution is, where a pH below 7 is acidic and a pH greater than 7 is basic. pH of 7 is considered neutral (e.g., pure water). Typically, values of pH range from 0 to 14, although very strong acids may have a negative pH, while very strong bases may have a pH exceeding 14. WebpH Indicator Ranges (Ascending pH) Acid-base pH indicators are solutions that have a characteristic color at certain pH levels. They are used to visually signal the acidity or alkalinity of an aqueous (water-based) solution. pH indicators generally change color over a range of two pH units.
