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.

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
