What is the [H+] in a solution with pOH of 0.253?
What is the concentration of hydrogen ions ([H^+]) in a solution with a pOH of 0.253? The following options are provided:
A: (5.58 \times 10^{-15} \, \text{M})
B: (1.79 \times 10^{-14} \, \text{M})
C: (3.21 \times 10^{-2} \, \text{M})
D: (5.58 \times 10^{-1} \, \text{M})

Okay so we know that pOH + pH = 14, so if pOH is 0.253 the pH would be 13.747.
And pH = -log [H+], so [H+] = 10^(-pH) –>This is just the antillog…
so [H+] = 1.791e-14, which would make sense for the strongly basic solution (so B is the correct answer)
Hope this helps…

14-.253=pH=13.74700
pH=-log[H+]
-13.74700=log[H+]
10^(-13.74700)=[H+]
1.79 × 10-14 =[H+]
