High Five Facts - PH Scale

The video tutorial covers five key facts about the pH scale. It explains that most liquids are either acids or bases, determined by their ion content. The pH scale ranges from 0 to 14, with acids below 7, bases above 7, and neutral at 7. Strong acids and bases are highly reactive and can be dangerous. Some acids, like stomach acid, are beneficial for digestion. The video also discusses tools for measuring pH, such as pH meters and indicator papers, which change color based on the pH level.
