Acids

=Acids by Evette Taylor=

At the simplest definition, an acid is any compound that yields hydrogen ions (H+) or hydronium ions (H3O+) when dissolved in water. Hydronium ions are really the combination of H+ ions and H2O molecules, i.e. H+ + H2O === H3O+.

 * Properties of Acids**
 * taste sour (don't taste them!)... the word 'acid' comes from the Latin //acere//, which means 'sour'
 * acids change litmus (a blue vegetable dye) from blue to red
 * their aqueous (water) solutions conduct electric current (are electrolytes)
 * react with bases to form salts and water
 * evolve hydrogen gas (H2) upon reaction with an active metal (such as alkali metals, alkaline earth metals, zinc, aluminum)
 * Examples of Common Acids**
 * citric acid (from certain fruits and veggies, notably citrus fruits)
 * ascorbic acid ([|vitamin C], as from certain fruits)
 * vinegar (5% [|acetic acid])
 * carbonic acid (for carbonation of soft drinks)
 * lactic acid (in buttermilk
