Sulfuric acid

•  Acid

  An acid (... from the Latin acidus meaning sour) is traditionally considered any chemical compound that, when dissolved in water, gives a solution with a hydrogen ion activity greater than in pure water, i.e. a pH less than 7.0 in its standard state. That approximates the modern definition of Johannes Nicolaus Brønsted and Martin Lowry, who independently defined an acid as a compound which donates a hydrogen ion (H) to another compound. Common examples include acetic acid and sulfuric acid.

•  Carboxylic acid

  Carboxylic acids are organic acids characterized by the presence of at least one carboxyl group, which has the formula -C(=O)OH, usually written -COOH or -CO2H. Carboxylic acids are Brønsted-Lowry acids — they are proton donors. Salts and anions of carboxylic acids are called carboxylates. The general formula of a carboxylic acid is therefore R-COOH, where R is some monovalent functional group.

•  Nitric acid

  Nitric acid, also known as aqua fortis and spirit of nitre, is a highly corrosive and toxic strong acid. Colorless when pure, older samples tend to acquire a yellow cast due to the accumulation of oxides of nitrogen. If the solution contains more than 86% nitric acid, it is referred to as fuming nitric acid. Fuming nitric acid is characterized as white fuming nitric acid and red fuming nitric acid, depending on the amount of nitrogen dioxide present.

•  Hydronium

  In chemistry, hydronium is the common name for the aqueous cation H3O, the type of oxonium ion, produced by protonation of water. It is the positive ion present when an Arrhenius acid is dissolved in water, as Arrhenius acid molecules in solution give up a proton (a positive hydrogen ion, H) to the surrounding water molecules (H2O). It is the presence of hydronium ion relative to hydroxide that determines a solution's pH.

•  Strong acid

  A strong acid is an acid that dissociates completely in an aqueous solution by losing one proton, according to the equation HA(aq) → H(aq) + A(aq) For sulfuric acid which is diprotic, the "strong acid" designation refers only to dissociation of the first proton H2SO4(aq) → H(aq) + HSO4(aq) More precisely, the acid must be stronger in aqueous solution than hydronium ion, so strong acids are acids with a pKa < −1.74.

•  Carbonic acid

  Carbonic acid (ancient name acid of air or aerial acid) has the formula H2CO3. It is also a name sometimes given to solutions of carbon dioxide in water, which contain small amounts of H2CO3. The salts of carbonic acids are called bicarbonates (or hydrogen carbonates) and carbonates. It is a weak acid. Carbonic acid should never be confused with carbolic acid, an antiquated name for phenol.

•  Perchloric acid

  Perchloric acid is the inorganic compound with the formula HClO4. Usually encountered as an aqueous solution, this colourless compound is a strong acid comparable in strength to sulfuric and nitric acids. It is useful for preparing perchlorate salts, especially ammonium perchlorate, an important rocket fuel. Perchloric acid is also dangerously corrosive and readily forms explosive mixtures.

•  Acid dissociation constant

  An acid dissociation constant, Ka, (also known as acidity constant, or acid-ionization constant) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction known as dissociation in the context of acid-base reactions. The equilibrium can be written symbolically as: HA File:Equilibrium.

•  Aqua regia

  Aqua regia or aqua regis (Latin for royal water or king's water) is a highly corrosive, fuming yellow or red solution, also called nitro-hydrochloric acid. The mixture is formed by freshly mixing concentrated nitric acid and concentrated hydrochloric acid, usually in a volumetric ratio of 1:3 respectively. It was named so because it can dissolve the so-called "royal metals," or noble metals, gold and platinum.

•  Boric acid

  Boric acid, also called boracic acid or orthoboric acid or acidum boricum, is a weak acid often used as an antiseptic, insecticide, flame retardant, in nuclear power plants to control the fission rate of uranium, and as a precursor of other chemical compounds. It exists in the form of colorless crystals or a white powder and dissolves in water. It has the chemical formula H3BO3, sometimes written B(OH)3. When occurring as a mineral, it is called sassolite.

•  Roncevaux Pass

  Roncevaux Pass (el. 1057 m. ) is a high mountain pass in the Pyrenees near the border between France and Spain. The pass itself is entirely in Spain. According to tradition, it is the site where Roland died during the Battle of Roncevaux Pass in 778, a landmark in Basque history leading to the foundation of the Kingdom of Pamplona. There is a tombstone near the pass commemorating the area where it is traditionally held that Roland died.
