An acid is any substance that in water solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions (acid catalysis).
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 ...
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 (\(\ce{HCl}\)) is an acid because it forms \(\ce{H^{+}}\) when it dissolves in water.
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). Acid Definition and Examples
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.
The Lewis definition of an acid states that it is a species that has a vacant orbital and therefore, has the ability to accept an electron pair. A Lewis base is a species that holds a lone pair of electrons and can, therefore, act as an electron-pair donor.

In chemistry, there are a few extremely common acid definitions that you may come across. Each describes acids as a whole, meaning they are not exclusive to specific acids. The definitions are known as Arrhenius acids, Bronsted Lowry acids, and Lewis acids.
In simple terms, acids are substances that taste sour and can turn blue litmus paper red, indicating their acidic nature. They’re known for their ability to react with bases to form water and salts, a fundamental reaction in chemistry.
