Some substances have a tendency to present a visible indicator (ordinarily, a adjust in colour) every time they detect the presence of the threshold concentration of some chemical species e.g., an acid. These substances are often called chemical indicators plus they possibly endure a chemical modify or simply a Bodily adjust to detect that.
