is it the first one ?? Given a solution with a pOH of 13.6, what is the [OH-] of the solution? 13.6 M 2.51 x 10-14 M 0.4 M 3.98 x 10-1 M

the relationship between [OH] and pOH is the same as the relationship between [H+] and pH\[pOH = -\log[OH^{-1}]\]and\[[OH^{-1}] = 10^{-pOH}\]

so is it the first one cause they are the same? @JFraser
JFraser
  • JFraser
if the concentration were the same thing as the pOH, there would be no need for both of them. They are not the same, the answer is not the first one

get a calculator and plug it in, there's no need to guess

i did it got .4
JFraser
  • JFraser
then you did it wrong

\[10^{-13.6}\] should be a whole lot smaller than 0.4
anonymous
  • anonymous
then it is the last one @JFraser
JFraser
  • JFraser
it's not the last one either
JFraser
  • JFraser
\(10^{-13.6}\) is incredibly small
anonymous
  • anonymous
its the second
JFraser
  • JFraser
it is, but you need to know how to calculate logarithm and antilog functions to properly calculate pH, pOH, [H+] and [OH-] concenrations
