Acid and Naming Acid --- By Nemo Jin

What are acids
--Chemical compounds that form solution containing hydrogen ions (H+).
--Hydrochloric acid is a strong acid.
--CH3COOH(vinegar) is a weak acid.



"aq"
--Refers to aqueous or "dissolved in water".
--Acid compounds usually only take one properties of acids when dissolved in water.



Naming Acid compounds
1.Naming acid compounds "--ate".
   All acids with oxygen and suffix "--ate".
   --Drop "hydrogen".
   --Drop suffix "-ate".
   --Add suffix "--ic acid" .
  EX. Hydrogen Carbonate ---- Carbonic acid


2.Naming Acids compounds "--ite"
   --Drop "Hydrogen".
   --Drop suffix "--ite".
   --Add suffix "-ous acid"..


3.Naming Acids compounds lacking oxygen
   --Drop hydrogen.
   --Add prefix "Hydro-".
   --Drop suffix "-ide".
   --Add suffix "-ic acid".



Weak versus Strong
--Strong acids, such as HCl dissociates completely into H+ and Cl+ ions.
--Weak acids, such as CH3COOH dissociates incompletely into H+ and CH3COO ions.


Law of Definite Composition (Proust's Law)
   --Chemical compound always has the same proportion of elements by mass.


Law of Multiple Proportion (Dalton's Law)
   --Same elements can combine in more than one proportion to form an compound.
