Definition Of Acids
An acid is a chemical substance whose aqueous solutions are characterized by a sour taste, the ability to turn blue litmus red, and the ability to react with bases and certain metals (like calcium) to form salts
More About Acids:-
Aqueous solutions of acids have a pH of less than 7A lower pH means a higher acidity, and thus a higher concentration of hydrogen ions in the solutionChemicals or substances having the property of an acid are said to be acidicCommon examples of acids include hydrochloric acid acetic acid (vinegar is a dilute solution of this liquid), sulfuric acid (used in car batteries), and tartaric acid (a solid used in baking)Acids can be solutions or pure substances, and can be derived from solids, liquids, or gasesAcids are corrosive to skin, but there are some exceptions to this rule. Strong acids and concentrated acids are corrosive. Boric acid and carbonates are not corrosiveThe Arrhenius definition defines acids as substances which increase the concentration of hydrogen ions (H+), or more accurately, hydronium ions (H3O+), when dissolved in waterAccording to Bronsted-Lowry definition an acid is a substance which can act as a proton donorA Lewis acid is a substance that can accept a pair of electrons to form a covalent bondExamples of Lewis acids includes all metal cations, and electron-deficient molecules such as boron trifluoride and aluminium trichlorideAcids can be tested with litmus, a natural indicatorLitmus is a purple dye, extracted from lichens, a plantWhen the litmus solution is neither acidic nor basic, its colour is purpleThere are two types of acids, mineral acids and organic acidsAn organic acid is an organic compound with acidic propertiesAmong acids, there are strong and weak acids. According to Arrhenius definition, strong acids are those which ionize in water completely and furnish protons and increase hydronium ion concentrations.

Answer:
you cannot define it
it comes under chemistry
Explanation:
acid in chemistrymeans any compound of hydrogen having more than 7 pH value
