equilibrium favors the (weaker/stronger) acid

weaker

a smaller pKa value means a (stronger/weaker) acid

stronger

which hybridization is most acidic?

sp

delocalization stabilizes the conjugate base, creating a (stronger/weaker) acid

stronger

as the inductive element gets (closer to/further from) the acidic hydrogen, the acidity of the molecule increases.

closer to

What is the acronym for the PEMDAS of determining relative acidity?

ARIO

If two atoms are in the same row, which is more acidic?

furthest right (more electronegative)

If two atoms are in the same column, which is more acidic?

lower, negative charge of the conjugate ion spread over a larger volume (more stable conjugate base)

if pH < pKa, a compound will exist in its (acidic/basic) form.

acidic

if pH > pKa, a compound will exist in its (acidic/basic) form.
