| carbolic acid | <chemistry> 1. A white or pinkish crystalline substance, C6H5OH, produced by the destructive distillation of many organic bodies, as wood, coal, etc, and obtained from the heavy oil from coal tar. It has a peculiar odour, somewhat resembling creosote, which is a complex mixture of phenol derivatives. It is of the type of alcohols, and is called also phenyl alcohol, but has acid properties, and hence is popularly called carbolic acid, and was formerly called phenic acid. It is a powerful caustic poison, and in dilute solution has been used as an antiseptic. 2. Any one of the series of hydroxyl derivatives of which phenol proper is the type. <chemistry> Glacial phenol, any one of a series of compounds having both phenol and aldehyde properties. Phenol phthalein. See Phthalein. Origin: Gr. To show + -ol: cf. F. Phenol. Source: Websters Dictionary (01 Mar 1998) |
| acid rain |
Rain containing droplets of nitric acid and sulfuric acid, formed when water molecules combine with gases such as sulfur dioxide (SO2) or nitrogen oxides (NOx)in the atmosphere and fall to Earth. Is especially harmful to fish and other aquatic life in rivers and lakes.

| acidity |
The level of hydrogen ion concentration in a solution. Acidity is measured on the pH scale. The pH scale is a logarithmic scale. The majority of readings go from 1 (very high acidity) to 14 (very high alkalinity).
