AP CHEM UNIT 8 RELATIVE ACID-BASE STRENGTHS

How is the strength of an acid determined based on Ka and Kb values?

The strength of an acid can be determined based on its acid dissociation constant (Ka) and the strength of its conjugate base (Kb). Higher Ka values indicate stronger acids, while higher Kb values indicate stronger bases.

What happens to the strength of binary acids as H-X bond energy decreases?

As the H-X bond energy decreases, the strength of binary acids increases.

How does the presence of oxygen affect the strength of oxyacids?

In oxyacids, strength increases as the number of oxygen atoms increases because the electron density is pulled away from the hydrogen atom.

What inductive effects influence acid strength?

The strength of an acid increases with electronegativity as the electron density is pulled away from the hydrogen atom

How does resonance affect the strength of carbonic acid?

More resonance structures in carbonic acid lead to greater delocalization of charge, resulting in a stronger acid.

How does the structure of nitrogenous bases affect their strength?

The strength of nitrogenous bases increases with the number of resonance structures, as increased resonance leads to greater stabilization of the base.
