An acid (from the Latin acidus/acÄre meaning sour) is a chemical substance whose aqueous solutions are characterized by a sour taste, the ability to turn blue litmus red, and the ability to react with bases and certain metals (like calcium) to form salts.he Swedish chemist Svante Arrhenius attributed the properties of acidity to hydrogen ions (H +) or protons in 1884. An Arrhenius acid is a substance that, when added to water, increases the concentration of H + ions in the water.
The surface of the inner wall of all of the body cavities is lined by a serous membrane which consists of a single layer of flat epithelium with a thin underlying propria (connective tissue). Within the thoracic cavity, this is known as the pleura. The visceral pleura which coats the outer surface of the lung is derived from the splanchnic mesoderm.
