If the OH- ion concentration in an aqueous solution at 25.0 °C has a value of 0.100 M, what is the pH of the solution?

Using the [OH^-], do this:
pOH = -log 0.100 = 1.000 (that's three sig figs in the answer because it's a log)
Next, use this equation:
pH + pOH = 14.000
pH + 1.000 = 14.000
pH = 13.000 (still three sig figs)
