Understanding pH Calculations: A Step-by-Step Guide Using t = 3 → pH = 8.1 − log₁₀(1 + 0.3×3) ≈ 7.82 When working with aqueous chemical systems, pH calculations are fundamental in determining acidity or alkalinity. A precise pH evaluation involves understanding logarithmic expressions and their real-world applications—just like the equation t = 3 → pH = 8.1 − log₁₀(1 + 0.3×3) ≈ 8.1 − 0.2788 = 7.82. ### Breaking Down the pH Formula The pH scale measures the concentration of hydrogen ions [H⁺] in a solution using the formula:
