Naming Acids

Acids are formed when a compound composed of Hydrogen ions and a negatively charged ion are dissolved in water. (aqueous)

  • ions seperate when they are dissolved in water
  • H+ ions joins with H2O to form H3O (hydronium ion)
Naming Guidelines

  1. Use "hydro" as the beginning
  2. The last syllable of the non-metal is dropped and replaced with "ic".
  3. Add "acid" at the end
*____ide --» hydro___ic acid

Complex Acids

  1. -ate is replaced with -ic                              *no hydro
  2. -ite is replaced with -ous
  3. "acid" at the end
An easy way to remember this:

"We ate ic-y sushi and got appendic ite ous."

Try some practice questions:
  1. NH4Cl
  2. Fe(NO3)3
  3. TiBr3
  4. Cu3P
  5. SnSe2
  6. GaAs
  7. Ph(SO4)2
  8. Be(HCO3)2
  9. Mn2(SO3)3
  10. Al(CN)3

  1. chromium (VI) phosphate
  2. vanadium (IV) carbonate
  3. tin (II) nitrite
  4. cobalt (III) oxide
  5. titanium (II) acetate
  6. vanadium (V) sulfide
  7. chromium (III) hydroxide
  8. lithium iodide
  9. lead (II) nitride
  10. silver bromide
