Acid and base are terms used by chemists to categorize chemicals according to their pH. An acid is generally considered to be any material that gives up a hydrogen ion in solution, while a base is any material that creates a hydroxide ion in solution....

(from Latin, acidus: sour) The term acid has multiple meanings. The more relevant scientific uses are: (1) in respect of taste (see TASTE PERCEPTION), acid means sour or sharp, as the etymology suggests. (2) In biology and chemistry, an acid is a...

A liquid that reacts with metallic oxides to form SALTS and water; reacts with (most) metals to produce salt and hydrogen; or reacts with carbonates to produce salts, CARBON DIOXIDE and water. Although they are not ELECTROLYTES in pure form, they...

Dextropimaric acid; d-Pimaric acid; α-Pimaric acid Occurs in the oleo-resins of Pinus spp. (Pinaceae), e.g., in French colophony and galipot, and American...

In computer science, ACID (Atomicity, Consistency, Isolation, Durability) is a set of properties that guarantee that database transactions are processed reliably. In the context of databases, a single logical operation on the data is called a...

Rescuers worked Saturday to save more dead and dying dolphins and sea lions that have washed up on Southern California beaches, believed poisoned by a naturally occurring toxic acid.A bloom of ocean algae that produces domoic acid may be responsible for killing or sickening dozens...

More than 80 cars from two trains derailed early Monday and one car leaked a powerful acid, releasing a vapor cloud that closed schools and forced hundreds of residents to evacuate. No injuries were reported.More than 350 people were evacuated from the path of the...

High doses of folic acid do not prevent precancerous colon polyps in people prone to them and may actually increase the risk of developing the growths, a new study finds.It's the latest evidence that taking too many vitamins may be harmful. Last month, a study...

An algae bloom in Southern California coastal waters has produced record levels of a toxic acid, scientists reported Wednesday. The chemical has been blamed in the deaths of numerous marine mammals and seabirds in recent months.Measurements from four coastal stations last month found the highest...

Details an experiment investigating the reactions of a typical acid (dilute hydrochloric acid) with metals, metal oxides, carbonates and bases. Concludes that acids and metal oxides form salt and hydrogen gas, while acids and carbonates form salts, water and carbon dioxide.

Acids and bases in household products give them their cleaning power, but have dangerous chemical properties that can physical harm.

Experiment to distinguish the difference of acids and bases and to found out what substances are acids and which are bases.
