Exam 1 Flashcards
Brønsted-Lowry base
Proton acceptor
Lower the pka
Stronger the acid
Stronger the acid
Weaker the conjugate base
Weaker the acid
Stronger the conjugate base
Pka values
Refer to individual protons
When giving the pka of a molecule
Refer to the most acidic proton
Equilibrium
Favors the side of the weaker acid
If equilibrium favors the products
Keq is greater than 1
If equilibrium favors reactants
Keq is less than 1
Down the periodic table (halogens column)
Size, stability and acidity increase
A negative pka value indicates
Majority of the molecules of the acid are dissociated in water
