Determining The Ph Values Of Acid Bases
I. Introduction
The purpose of this experiment is to determine the pH values of acids, bases, and buffers of distilled water and 10.0 buffer using measured concentrations of Sodium hydroxide (NaOH) and/or Hydrochloric acid (HCl). Acid is a compound typically having a bitter taste and capable of nullifying alkalis and releases hydrogen ion when added to a solution, or containing an atom that can accept a pair of electrons from a base (McKinley, Dean O’Loughlin, & Stouter Bidle, 2016). Bases are water-soluble and are harsh tasting compounds, that are capable of accepting a hydrogen ion, and are molecules or ions capable to take up a proton from an acid or able to give up an unshared pair of electrons to an acid (McKinley, Dean O’Loughlin, & Stouter Bidle, 2016). These two mechanisms together help the human body to stay balanced. The pH scale will help determine which direction the body is leaning towards; the base or the acid. The body has a buffering system to help regulate the process called homeostasis. The role of a buffer system as a homeostatic mechanism that maintains the pH of body fluids.

When Sodium Hydroxide (NaOH) is added to distilled water, it separates into Na (+) and OH (-). The pH rose due to as more and more base (NaOH) was added to the solution as expected. The sodium doesn't affect the pH of the solution, but all of the OH (-) ions will make the pH increase higher as the solution becomes more basic. That is why the pH increased. The values of how acids and bases answer in water make the foundation of the pH scale. The hypothesis does not to be altered due to the research and experimenting of acids and bases supporting why the pH levels had increase each time when drops where
