Acid Base Indicator
A compound that changes color when exposed to an acid or a base, like litmus paper
Real World Example
Imagine you're trying to decide what outfit to wear based on the weather outside. Just like checking the sky to see if it's sunny or cloudy helps you decide whether to wear sunglasses or carry an umbrella, an acid-base indicator helps determine if a solution is acidic or basic by changing color. In this analogy, the sky acts as the solution, your outfit choice represents the color change of the indicator, and the presence of sun or clouds corresponds to whether the solution is an acid or a base.
