Acids & Bases Flashcards
How many definitions are there of acids & basis?
3
What is Arrhenius definition of acids?
Releases H+ in solution
What is Arrhenius definition of basis?
Releases OH- in solution
What is the bronsted- Lowry definition of acids?
H+ donor
What is the bronsted- Lowry definition of bases?
H+ acceptor
What is the conjugate acid? (Bronsted-lowry)
What receives the H+
What is the conjugate bases? (Bronsted-lowry)
What has lost the H+ & thus can now receive one
What is the Lewis definition of acid?
Electron pair acceptors (ecectrophices)
What is the Lewis definition of bases?
Electron pair donor (nucleophile)
What is the easiest way to identify which is a Lewis acid & base?
Draw the Lewis structure
What is a strong acid? How can you tell from a reaction equation?
Acid that fully dissociates and are strong electrolytes (conduct electricity better than weak acids), so reaction arrow going one way not both
What is a weak acid? How can you tell from a reaction equation?
Partial dissociated into ions, weak electrolytes ( electrical conductivity depends on extent of ionization), equation arrows are equilibrium arrows
What is a strong base? How can you tell from a reaction equation?
Base that fully dissociates and are strong electrolytes (conduct electricity better than weak bases), so reaction arrow going one way not both
What is a weak base? How can you tell from a reaction equation?
Partial dissociated into ions, weak electrolytes ( electrical conductivity depends on extent of ionization), equation arrows are equilibrium arrows
