Emäksiä

Emäksiä is a Finnish term often translated as "bases" in chemistry. In the context of chemistry, an emäs is a substance that can accept protons (H+) or donate electrons. This definition aligns with the Brønsted-Lowry and Lewis theories of acids and bases. In aqueous solutions, emäksiä typically increase the concentration of hydroxide ions (OH-). Common examples of emäksiä include sodium hydroxide (NaOH) and potassium hydroxide (KOH).

The reaction of an emäs with an acid is called neutralisation, which results in the formation of a salt and water. This process is fundamental to many chemical reactions and industrial processes. The strength of an emäs is determined by its ability to dissociate in water and release hydroxide ions or accept protons. Strong emäksiä, like those mentioned earlier, dissociate completely, while weak emäksiä only partially dissociate.

In a broader sense, the term "emäs" can also refer to a fundamental or principal component of something. This usage is less common in scientific contexts but can be found in more general discussions. However, in chemistry, it consistently refers to substances exhibiting basic properties according to established chemical definitions. The pH scale is used to measure the acidity or basicity of a solution, with values above 7 indicating an emäksinen or alkaline solution.
