Chapter 4 Flashcards
Amphoteric
Able to act as an acid or a base.
Strong acid
Totally dissociates in water
Weak acid
Does not fully dissociate in water
Lewis Acid
Molecule that accepts electrons
Lewis Base
Molecule that donates electrons
Bronsted Lowry base
Molecule that accepts proton. (H+)
Bronsted Lowry Acid
Molecule that donates proton.(H+)
Smaller Ka Value
Weaker Acid
Larger Ka Value
Stronger Acid
Smaller pKa Value
Stronger Acid
Larger pKa Value
Weaker Acid
Protonated Molecules are more acidic
True
Protonated Molecules are less acidic
False
Factors that effect pKa (acidity)
Electronegativity
Hybridization
Size of atom
Resonance
Orbital Hybridization Electronegativity
sp > sp2 > sp3
Direction of equilibrium
toward weaker acid
Stable base is a weak base
True
Stable base is a strong base
False
Stronger the acid, stronger the conjugate base
False
Stronger the acid, weaker the conjugate base
True
Stronger the base the weaker the conjugate acid
True
Stronger the base the stronger the conjugate acid
False
