Q

pOH and OH- Relationships

A
  • expresses OH- concentration as the negative logarithm of the OH- concentration in moles per liter
  • pOH = -log[OH-]
  • [OH-] = 10^-pOH
2
Q

what is the pOH of a 4.8*10^-3 M OH- solution?

A
  • pOH = -loh[OH-]
  • pOH = -log[4.8*10^-3]
  • pOH = 2.32
3
Q

what is the [OH-] if hte pOH is 11.34?

A
  • [OH-] = 10^-pOH
  • [OH-] = 10^-11.34
  • [OH-] = 4.6*10^-12 M OH-
