PH

Real World Example

Imagine trying to decide how spicy a dish is by tasting it. Just like measuring spiciness helps you understand how much chili is in your food, measuring pH helps you understand how many hydrogen ions are in a solution. The spiciness of a dish, akin to the acidity or basicity of a solution, is determined by the concentration of a specific ingredient—in the case of pH, it's the hydrogen ions, which define how acidic or basic the solution is.
