Keq is never:
negative or positive? - Negative
- delta pKa =
- -log Keq
- Weaker acid has higher or lower pKa?
- higher pKa
- The closer an electonegative atom is to the main H, the (higher or lower) the acidity?
- Higher acidity
- Overlap of atoms of similar size results in a (higher/lower) bond strength?
- Higher
- Lewis acid
-
accepts electon pair
(acid accepts) - Lewis base
- donates electron pair
-
Higher s character means better positive interaction because __________________
___________. - the electron closer to nucleus, thus the electronegativity is higher and the acidity is higher.
- Ka =
- [H+][A-]/[HA]
- pKa=
- -log(subscript 10)Ka
- A strong acid ionizes completely. T/F
- T
