Hydrochloric acid, also known as muriatic acid or spirits of salt, is an aqueous solution of hydrogen chloride (HCl). It is a colorless solution with a distinctive pungent smell. It is classified as a strong acid. It is a component of the gastric acid in the digestive systems of most animal species, including humans.
Spiritus fumans – stannic chloride, formed by distilling tin with corrosive sublimate. Spirit of hartshorn – ammonia, formed by the decomposition of sal-ammoniac by unslaked lime. Spirit of salt/ acidum salis – the liquid form of hydrochloric acid (also called muriatic acid), formed by mixing common salt with oil of vitriol.
A mixture of organic acids (resin acids, predominantly abietic acid, with pimaric acid, isopimaric acid, neoabietic acid, dihydroabietic acid, and dehydroabietic acid), rosin is a glassy solid, virtually nonreactive and noncorrosive at normal temperature, but liquid, ionic and mildly reactive to metal oxides at molten state. Rosin tends to ...
Hydrazoic acid: used primarily for preservation of stock solutions, and as a reagent Hydrochloric acid: a highly corrosive, strong mineral acid with many industrial uses Hydrofluoric acid: valued source of fluorine, precursor to numerous pharmaceuticals; highly corrosive Hydrogen peroxide: an oxidizer commonly used as a bleach Imidazole
A mineral acid (or inorganic acid) is an acid derived from one or more inorganic compounds, as opposed to organic acids which are acidic, organic compounds. All mineral acids form hydrogen ions and the conjugate base when dissolved in water.
Here, fresh aqua regia has been added to these NMR tubes to remove all traces of organic material. Aqua regia (/ ˈ r eɪ ɡ i ə, ˈ r iː dʒ i ə /; from Latin, "regal water" or "royal water") is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. [b] Aqua regia is a fuming liquid.
Again, copper has no reaction with dilute sulfuric acid, but in concentrated sulfuric acid, the highly acidic environment and high concentration of sulfate ions allow the sulfate ions to act as an oxidizing agent. [2] Sulfuric acid is not an oxidizing agent, but the sulfate ion is a very weak oxidizing agent.
One can see bubbles of gaseous O 2 formed by the coalescence of nascent atomic oxygen produced by the reaction between hydrogen peroxide and sulfuric acid. Piranha solution is used frequently in the microelectronics industry, e.g. to clean photoresist or organic material residue from silicon wafers .
