PH strips are small strips of specially treated paper that change color when dipped into a liquid. The color change indicates the pH level, showing whether the substance is acidic, neutral, or alkaline (basic). They provide a quick, simple, and inexpensive way to measure pH in laboratories, healthcare, education, water testing, and other applications.
