  • 1 answers

Gaurav Seth 5 years ago

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. An acid is basically a molecule which can donate an H+ ion and can remain energetically favourable after a loss of H+. Acids are known to turn blue litmus red.

Properties of Acids

  • Acids are corrosive in nature.
  • They are good conductors of electricity.
  • Their pH values are always less than 7.
  • When reacted with metals, these substances produce hydrogen gas.
  • Acids are sour-tasting substances.
  • Examples: Sulfuric acid [H2SO4], Hydrochloric acid [HCl], Acetic acid [CH3COOH].
