Video: Acid Base Indicator simple definition.
Imagine you're trying to determine whether a pot of soup is too salty or not salty enough just by tasting it. Just as your taste buds help you detect the saltiness level, an acid-base indicator like litmus paper helps detect whether a solution is acidic or basic by changing color. Much like how your taste buds signal the need for more or less salt, the litmus paper changes its hue to signal whether the solution is acidic (turning red) or basic (turning blue), acting as a sensory guide in a chemical context.
