i need help with this question.

What pH corresponds to each of the following: (a) (H-)=7.3*10^-5M, (b)(H+)=0.084M,(c)(OH-)= 3.3*10^-4M, (d) (OH-)= 0.042M?

Thank you.

  • chemistry -

    a.
    pH = -log(H^+)
    pH = -log(7.3 x 10^-5)
    pH = -(-4.14)
    pH = 4.14

    For questions involving OH, just find pOH from the (OH^-), then use pH + POH = 14
