is a measure of the tendency of a compound to lose a proton

Answer 10

Acidity

Question 11

is a measure of a compound’s affinity for a proton

Answer 11

Basicity

Question 12

A _______ ____ has a strong tendency to lose a proton; thus, its conjugate base is weak because it has little affinity for the proton.
