how do you determine pH knowing hydrogen ion concentration?
PH= -log[H+] therefore H+= 10^(-pH)
What is the Henderson hasselbalch equation?
PH= pKa + log (acid/base)
What is Ka?
The acid dissociation constant
What is the case when PH=PKa?
Acid and base have equal concentration within the solution
What does a buffer do?
Resists change in pH
