Calculating the pH of Buffer Solutions There are two methods to calculate the pH of a buffer solution, by using (1) the equilibrium method or by using (2) the Henderson-Hasselbach equation. 1. The Equilibrium Method Consider the buffer solution below. Chemistry is the branch of science that studies the properties of matter and how matter interacts with energy. Chemistry is considered a physical science and is closely related to physics. Sometimes chemistry is called the "central science" because it is an important part of other major sciences such as biology, Earth science, and physics.

We know a structure of an atom consists of electrons, protons, and neutrons. This was accurately presented after several scientists came up with different models. The classic model of an atom was given by Ernest Rutherford called the Rutherford atomic model or Rutherford model of the atom.
