Study Notes

Strong Acids

  • HCl (Hydrochloric acid) is classified as a strong acid.
  • HBr (Hydrobromic acid) is recognized as a strong acid.
  • HI (Hydriodic acid) is another example of a strong acid.
  • H2SO4 (Sulfuric acid) is also a strong acid.
  • HClO4 (Perchloric acid) is considered a strong acid.
  • HClO3 (Chloric acid) falls into the category of strong acids.

Weak Acids

  • HF (Hydrofluoric acid) is categorized as a weak acid.
  • HC2H3O2 (Acetic acid) is a well-known weak acid.
  • H3PO4 (Phosphoric acid) is classified as a weak acid.
  • H2CO3 (Carbonic acid) is also a weak acid.
  • HCN (Hydrogen cyanide) is a weak acid.
  • HClO2 (Chlorous acid) is considered a weak acid.
  • HClO (Hypochlorous acid) is classified as a weak acid.

Reaction Characteristics

  • Strong acids fully dissociate in reactions, proceeding to completion.
  • Weak acids partially dissociate, establishing an equilibrium in reactions.

Strong Bases

  • LiOH (Lithium hydroxide) is categorized as a strong base.
  • NaOH (Sodium hydroxide) is recognized as a strong base.
  • KOH (Potassium hydroxide) is classified as a strong base.
  • HNO3 (Nitric acid) is another strong acid, complementing strong basics.
  • PbOH (Lead hydroxide) is categorized as a strong base.
  • Mg(OH)2 (Magnesium hydroxide) is recognized as a strong base.
  • Ca(OH)2 (Calcium hydroxide) is also classified as a strong base.

Identifying Strong and Weak Acids/Bases

  • Strong acids typically have at least two more oxygen atoms than hydrogen atoms.
  • Weak bases often contain nitrogen or carbon in their structure.
  • NH3 (Ammonia) is identified as a weak base.
  • CH3NH2 (Methylamine) is recognized as a weak base.
  • CH3Cl2NH3 (a derivative of ammonia) is also categorized as a weak base.
