Section 15.2- Strengths of Acids and Bases Flashcards
The extent to which acids ionize in solution
Strength
Acids that ionize completely to form H3O + and a conjugate base in aqueous solution
Strong acids
Ionize only partially ( double arrows in equation)
Weak acids
Strong acids list:
- H2SO4 — sulfuric acid
- HNO3– nitric acid
- HClO4— perchloric acid
- HCl— hydrochloric acid
- HBr— hydrobromic acid
- HI— hydroiodic acid
Strong bases list:
- NaOH- sodium hydroxide
- KOH— potassium hydroxide
- LiOH— lithium hydroxide
- Ba(OH)2— barium hydroxide
- Ca(OH)2 — calcium hydroxide
Bases that completely dissociate into hydroxide ions in aqueous solution
Strong bases
The most familiar weak base
Ammonia
The terms weak and strong refer to the extent of ___________ of an acid or base, not to its _____________
Ionization
NOT concentration
The stronger the acid or base, the ________ its conjugate base or acid
Weaker
Proton transfer reactions favor the formation of the
Weaker base and the weaker acid
Stronger acid + stronger base ———->
Weaker acid + weaker base. <—-
Weaker acid + weaker base —->
Stronger acid + stronger base <————
