Acids are formed when a compund of Hydrogen Ions and a negitively charged ion are dissolved in water(aqueous). Ions separate when they are dissolved in water.
H + Cl -> HCl(g)
HCl(g) + H2O(l) -> H3O(aq) + Cl(aq)
Naming Acid Guidlines
1. Use "hydro" as the beginning
2. Last syllable of the non-metal is dropped and replaced with "-ic"
3. Add "acid" at the end
* ide -> hydro ic acid*
HF becomes hydro flouric acid
Naming Complex Acids
1. -ate is replaced with -ic
-ite is replaced with -ous
2. "acid" at the end of the name
HCH3COO becomes Acetic Acid
