Acid, any substance that in water solution tastes sour, changes the color of certain indicators (e.g., reddens blue litmus paper), reacts with some metals (e.g., iron) to liberate hydrogen, reacts with bases to form salts, and promotes certain chemical reactions (acid catalysis).
An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule or ion able to accept a hydrogen ion from an acid. Acidic substances are usually identified by their sour taste.
The meaning of ACID is a sour substance; specifically : any of various typically water-soluble and sour compounds that in solution are capable of reacting with a base to form a salt, redden litmus, and have a pH less than 7, that are hydrogen-containing molecules or ions able to give up a proton to a base, or that are substances able to accept ...
noun. Chemistry. a compound usually having a sour taste and capable of neutralizing alkalis and reddening blue litmus paper, containing hydrogen that can be replaced by a metal or an electropositive group to form a salt, or containing an atom that can accept a pair of electrons from a base.
An acid is a substance that forms hydrogen ions H + when dissolved in water, and. A base is a substance that forms hydroxide ions OH - when dissolved in water. For example, hydrochloric acid ( HCl HCl) is an acid because it forms H+ H + when it dissolves in water. HCl(g) Water H+(aq) +Cl−(aq) H C l ( g) Water H + ( a q) + C l − ( a q)

Jan 13, 2020 · An acid is a chemical species that donates protons or hydrogen ions and/or accepts electrons. Most acids contain a hydrogen atom bonded that can release (dissociate) to yield a cation and an anion in water. The higher the concentration of hydrogen ions produced by an acid, the higher its acidity and the lower the pH of the solution.
Feb 14, 2023 · An acid is a hydrogen ion or proton donor or an electron pair acceptor. Not all compounds containing hydrogen are acids. Acids have a pH less than 7, turn litmus paper red, taste sour, and react with bases. Examples of acids include hydrochloric acid (HCl), sulfuric acid (H 2 SO 4 ), and acetic acid (CH 3 COOH).
noun. /ˈæsɪd/. /ˈæsɪd/. [uncountable, countable] (chemistry) a chemical, usually a liquid, that contains hydrogen and has a pH of less than seven. The hydrogen can be replaced by a metal to form a salt.
An acid is a substance that can donate a hydrogen ion (H +) (generally speaking, this will be a proton) to another substance. Acids have a pH less than 7.0. A chemical can donate a proton if the hydrogen atom is attached to an electronegative atom like oxygen, nitrogen, or chlorine. Some acids are strong and others are weak.
