How Buffers Resist pH Change: The Henderson-Hasselbalch Equation
See how a weak acid and its conjugate base hold pH steady, with the Henderson-Hasselbalch equation and worked numbers for acetate and blood.
AcidsHow the pH Scale Works: Logarithms, Water and Real Solutions
Understand how pH measures hydrogen ion concentration on a logarithmic scale, why water sets neutral, and how to calculate pH for strong and weak acids.
