pH range vs. color change for acid and base indicators - together with pKa and structures of the indicators.
You may have heard that citrus juices are acids or that ammonia is a base. The terms acid and base refer to the concentration of hydrogen ions (pH) in the substance; acids have a high concentration of hydrogen ions, while bases have a low concentration o
