What is pH and How is it Measured?

The pH scale, developed by Danish biochemist Søren Peter Lauritz Sørensen in 1909, represents a fundamental concept in chemistry that quantifies the acidity or alkalinity of a substance. This logarithmic scale spans from 0 to 14, where each whole number represents a tenfold difference in hydrogen ion concentration—an elegant mathematical framework that belies its practical significance in our daily lives.

Understanding the pH Scale

The term "pH" stands for "potential of hydrogen," reflecting its measurement of hydrogen ion activity in a solution. On this spectrum:

• Acidic substances register below 7 (higher hydrogen ion concentration)
• Neutral substances hover precisely at 7
• Alkaline or basic substances measure above 7 (lower hydrogen ion concentration)

The pH measurement is mathematically expressed as:

pH = -log₁₀[H⁺]

Where [H⁺] represents the concentration of hydrogen ions in moles per liter. This logarithmic nature explains why even small numerical changes on the scale reflect significant differences in acidity or alkalinity.

Measuring pH in Foods

Scientists employ several methods to determine the pH of foods like bananas:

1. pH Meters: Electronic devices featuring a glass electrode that provide precise readings
2. Litmus Paper: Paper strips impregnated with indicators that change color based on pH
3. Universal Indicators: Solutions that exhibit a spectrum of colors corresponding to different pH values
4. Potentiometric Titration: A laboratory technique for highly accurate measurements

pH and Human Health

Our bodies maintain rigorous pH control systems—blood typically remains between 7.35 and 7.45, slightly alkaline. The stomach, conversely, produces hydrochloric acid, creating a highly acidic environment (pH 1.5-3.5) essential for digestion. Understanding food pH becomes paramount for individuals with conditions like:

• Gastroesophageal reflux disease (GERD)
• Acid reflux
• Erosive esophagitis
• Peptic ulcers
• Sensitive digestive systems

pH and Food Preservation

Beyond health implications, pH fundamentally influences food safety and preservation. Foods with lower pH values (more acidic) typically resist microbial growth more effectively. This explains why many preserved foods contain acidic ingredients like vinegar or citric acid—they create inhospitable conditions for potential pathogens.

This distinction between inherent pH and metabolic effect lays crucial groundwork for our examination of bananas—where their measured acidity tells only part of a more intricate nutritional story. 🧪📊
