Educational Information and Applications of pH

Introduction

Understanding pH is fundamental in chemistry and many practical applications. This guide covers key formulas, pH ranges, and common applications.

Key Formulas

• pH = -log₁₀[H⁺]
• [H⁺] = 10⁻ᵖᴴ
• pH + pOH = 14 (at 25°C)
• Kw = [H⁺][OH⁻]

pH Ranges

• 0-6.9: Acidic
• 7.0: Neutral
• 7.1-14: Basic

Applications of pH

• Water quality testing
• Aquarium maintenance
• Food & beverage industry
• Laboratory analysis

Why pH Matters

• pH affects chemical reactions, biological processes, and environmental conditions.
• Monitoring pH is crucial in many industries for safety and quality control.
