📖 1. Universal pH Scale

🔑 Key Concepts & Definitions

• Universal indicator: A chemical solution that changes color to show the pH level of a solution, allowing the pH scale to be visually represented (source content).
• pH scale from 0 to 14: A numerical scale that measures the acidity or alkalinity of a solution, where 0 indicates the most acidic, 7 is neutral, and 14 is most alkaline (source content).
• Acidic solution pH < 7: A solution with a pH value less than 7, indicating it is acidic, often releasing H+ ions in solution (source content).
• Neutral solution pH = 7: A solution with a pH of exactly 7, indicating it is neither acidic nor alkaline, typically water (source content).
• Alkali solution pH > 7: A solution with a pH greater than 7, indicating it is alkaline or basic (source content).
