YOGYAKARTA - In everyday life, without realizing it, we have actually witnessed or experienced firsthand the phenomenon of basal acid theory. This base acid we can find in fruits that contain acid, as well as soap or determinants that have base properties. Types of fruits such as oranges have an acidic taste because there are acidic properties in them. Meanwhile, soap, although it is not classified as an ingredient to eat, but if you feel, soap has a bitter taste and slippery texture. This is due to the presence of baseline properties contained in soap. This article will discuss base acids with Arrhenius base acid theory. Watch more fully below.

Swedish Kimiawan Svante Arrhenius is called the first originator of base acid theory. Arrhenius sparked a base acid theory in 1884. In his research, Arrhenius revealed that when acid is an substance, then put in water it will produce a hydronium ion or H+.

The acid is also referred to as a polar covalent that can dissolve when mixed with water. The acids that produce perfect hydroxide ions are called strong acids, as for the imperfect acids in the ionization process so that they produce small hydroxide ions called weak acids.

Arrhenius then defines a base as a substance capable of producing hydroxide ions (OH-) when mixed into water. However, although it can dissolve into water, this base is different from acid because the resulting ions are also different.

For example, when a sodium hydroxide and hydroxide amonium are dissolved, it will produce many hydroxyl or OH- ions. The results of the many hydroxyl ions are referred to as strong bases, some of which are referred to as weak bases. However, the theory of Arrhenius base acids has a deficiency that does not apply to solvents other than water.

Formulas commonly used in base acid theory aim to find a level of acidity by knowing the level of concentration of hydrogen ions or H+ in solution. The level of ion concentration is notated as pH. The pH symbol comes from p which means power or potenz, while H to symbolize hydrogen atoms.

The equations that can be used to increase the level of acidity are:

pH = -log(H+)

From the above presentation, we can conclude that the theory of Arrhenius states acid is a compound that can produce hydroxide ions or H+ when dissolved in water. While bases produce hydroxyl ions or OH-. Furthermore, the theory of Arrhenius also explains that acids will produce one H+ of each molecule and are called monoprotic acids.

As for acids that produce two H+s, we call them diprotic acids. While acids that produce three H+ per molecule are called triprotics. Meanwhile, in general, if hydrogen ions produced by acids are dissolved more than one by one molecule, then they are called polyprotics.
