ORGANIC ACIDS Obtained from plants and animals These are weak acids, acetic acid MINERAL ACIDS Obtained from minerals These are generally strong acids,eg HCl.

 Acids are the substances which can give hydrogen ion in aqueous solution.  HCl (aq) H+ + Cl-  H 2 SO 4 (aq) 2H+ + Cl-

More to learn about acids  Acids are good conductor of electricity as they can give hydrogen ion in aqueous solution.  Acids are colourless in aqueous solution.  Acids give red colour with methyl orange.
