What Are Indicators & How Do We Use Them?

The video tutorial explains how to determine the pH of a solution using indicators. It covers universal indicators, which show a range of colors across the pH scale, and specific indicators like litmus, phenolphthalein, and methyl orange, each with distinct color changes at certain pH levels. The tutorial concludes with a summary of how indicators work and their importance in identifying the pH of solutions.
