How do strong and weak acid's dissociation equations compare?
HA(aq) → H+ + A-
HA(aq) ⇔ H+ + A-
What is the acid dissociation constant?
An expression used for weak acids
What is the purpose of pKa?
- Ka gives small, negative indicies which are difficult to compare
pKa = -logKa
As Ka gets larger, the acid is a stronger weak acid
As pKa gets smaller, the acid is a stronger weak acid
