Answer:

1.79x10^-14

Explanation:

pOH + pH = 14

H+=10^-pH

- Hope that helps! Please let me know if you need further explanation.

Answer:

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...
