Naming ACIDS

Acids taste sour, are corrosive to metals, change litmus (a dye extracted from lichens) red, and become less acidic when mixed with bases.  They are formed when a compound made out of HYDROGEN ions and a negatively charged ion are dissolved in water (aqueous (aq) ).

NAMING ACIDS GUIDELINES (SIMPLE ACIDS)
*simple acids are acids formed from the elements on the periodic table.

  1. "Hydro" is the beginning of the name.
  2. The last syllable of the non metal is dropped and replaced with "-ic"
  3. The last step is to add "acid" at the end and your done naming your acid:)
Ex:
 ♥  HCL    ⇒   Hydrochloric acid
 ♥  H₂S     ⇒   Hydrosulphuric acid **

NAMING COMPLEX ACIDS
*complex acids are acids formed with polyatomic anions

  1. "- ate" if the anion name ends in "- ic"

♥"- ous" if the anion name ends in "- ite"
     2.  Then add acid at the end of the name.


Ex.
♥  H2SO4    ⇒   sulphuric acid
          ♥  HNO2       ⇒   nitrous acid


Joke:
A physicist, biologist and a chemist were going to the ocean for the first time.
The physicist saw the ocean and was fascinated by the waves. He said he wanted to do some research on the fluid dynamics of the waves and walked into the ocean. Obviously he was drowned and never returned.
The biologist said he wanted to do research on the flora and fauna inside the ocean and walked inside the ocean. He too, never returned.
The chemist waited for a long time and afterwards, wrote the observation, "The physicist and the biologist are soluble in ocean water".
