|
|
What is Acid
|
produces H or donates H
|
|
|
What is Base
|
produces OH or accepts H
|
|
|
pKa =
|
pKa = -logKa
|
|
|
What is Ka
|
dissociation constant indicating extent of ionization of a weak acid
|
|
|
When does K value increase
|
K increase as tendance of acid to dissociate
|
|
|
What is buffers made of?
|
weak acid and it's conjugate base
|
|
|
What do buffers do
|
minimizes pH change
|
|
|
when is pH of buffer = pKa
|
when the [ ] of weak acid and conjugate base is = (or 50% dissociated)
|
|
|
Henderson Hassel bach equation
|
pH= pKa + log A/HA
pH = pKa + log base/acid |
