Acid (Archival)

In chemistry, a substance capable of forming hydrogen ions when dissolved in water. Acids can weaken cellulose in paper, board, and cloth, leading to embrittlement. Acids may be introduced in the manufacture of library materials and may be left in intentionally (as in certain sizings) or incidentally. Acids may also be introduced by migration from other materials or from atmospheric pollution. See also pH and Acid migration.

Acid (Beauty)

Acids are used in skin care products to stabilize formulas that have an unwanted alkaline level. Its purpose is to change the pH level of a substance.

Acid (Car Care)

In a restricted sense, any substance containing hydrogen in combination with a nonmetal or nonmetallic radical and capable of producing hydrogen ions in solution.

Acid (Car Wash)

A chemical substance whose properties include the ability to react with bases or alkalies in water solutions to form salts.

Acid (Chemistry)

A compound that yields H+ ions in solution or a solution in which the concentration of H+ exceeding OH-.

Acid (Coffee)

A normal characteristic of arabica coffees, particularly of high-growth varieties. Some strains are sought for this particular taste (Kenya), which is influenced by the degree of roasting and does not seem to be objectively expressed by pH measurement. Experts recognize three types of acidity: 1) natural desirable: acid, 2) natural undesirable: sour, and 3) undesirable: process acidity (sometimes sought as a substitute for natural acidity but generally has a biting, puckery flavor.

Acid (Corrosion)

A chemical substance that yields hydrogen ions (H+) when dissolved in water. Compare with base.

Acid (Dream)

To drink any acid is an adverse dream, bringing you much anxiety.
For a woman to drink aciduous liquors, denotes that she may ensnare herself with compromising situations; even health may be involved.
To see poisonous acids, some treachery against you may be discovered.

Acid (Drug Rehabilitation)

Common street name for LSD.

Acid (Drugs)

LSD

Acid (EU Aerospace Acronyms)

Aircraft Identification

Acid (Environment)

A corrosive solution with a pH less than 7.

Acid (Food)

A substance having a sour or sharp flavor. Most foods are somewhat acidic. Foods generally referred to as "acids" include citrus juice, vinegar, and wine. A substance's degree of acidity is measured on the pH scale; acids have a pH of less than 7.

Acid (Food Safety)

A substance with a pH below 7.0. Acidic substances include lemons (pH 2.4) and mayonnaise (pH 3.0).

Acid (Health and Beauty)

Acids are used in skin care products to stabilize formulas that have an unwanted alkaline level. Its purpose is to change the pH level of a substance.

Acid (Hippy)

D- lysergic acid diethylamide tartrate, a chemical compound which induces changes in levels of consciousness. Many of us in the Haight assumed that it works through the pineal gland, which we called The Third Eye after the Tibetans. Entering through this concentrated tool of consciousness, we thought that it opened up neural pathways in otherwise unutilized portions of the brain. Unfortunately research on how this amazing substance really works has been very limited due to the general paranoia of the government. For excellent information on Dr. Albert Hofmann, the Swiss chemist who discovered the psychedelic properties of LSD while doing research for Sandoz Laboratories, and for the molecular and physical properties of LSD, I recommend Psychedelics Encyclopedia by Peter Stafford. (see book list).

Acid (Import Cars)

An acronym for a four-mode, driving-test cycle used to test exhaust emissions or vehicle driveability; the modes are Accelerate, Cruise, Idle, and Decelerate.

Acid (Java)

The acronym for the four properties guaranteed by transactions: atomicity, consistency, isolation, and durability.

Acid (Naturopathic)

In our context, a substance having a pH below that of neutral water (7.0) when in solution. Most metabolic waste products are acidic. Sour. See pH.

Acid (Nutrition)

A water-soluble substance with sour taste. An acid is any class of compounds that share certain basic chemical characteristics. Acids found in plant tissues (especially fruits) tend to prevent the secretion of fluids and shrink tissues.

Acid (Physical Geography)

(1) Substance having a pH less than 7.
(2) Substance that releases hydrogen ions (H+).

Acid (Plumbing)

A substance that increases the concentration of hydrogen ions when dissolved in water. Most acids dissolve common metals and will react with a base to form a salt.

Acid (Pool and Spa)

A chemical that is used to lower the pH and/or total alkalinity. Most commonly used are liquid muriatic acid (hydrochloric acid) or granular pH decreaser (sodium bisulfate).

Acid (Sanitation)

(1) A substance that tends to lose a proton. (2) A substance that dissolves in water with the formation of hydrogen ions. (3) A substance containing hydrogen which may be replaced by metals to form salts.

Acid (Tree)

pH - acidity or alkalinity ranging from 3 (strongly acid) to 11 (strongly alkaline) with 7 being neutral.

Acid (Volcano)

A descriptive term applied to igneous rocks with more than 60% silica (SiO2).

Acid (Water Science)

A substance that has a pH of less than 7, which is neutral. Specifically, an acid has more free hydrogen ions (H+) than hydroxyl ions (OH-).
