can't help you if you dont post your doubt/question

OpenStudy (aaronq):
use the relationship: \(pH=-log[H^+]\)
OpenStudy (anonymous):
B?
OpenStudy (aaronq):
if you havent worked with logarithms, to find \([H^+]\), you rearrange the equation to:
\([H^+]=10^{-pH}\)

yes

I think this one is B, is that right?
OpenStudy (aaronq):
yeah
OpenStudy (anonymous):
xD Any more questions? Sorry. Didn't get here in time.

pH=-log[H+]
pOH=-log[OH-]
10^-14=[H+][OH-]
Those 3 equations might help.

I think this one might be acidic? sorry I need to get these right?
OpenStudy (anonymous):
Dang it I was wrong!! haha

Well the pH is 10... I'm pretty sure that makes it an base. 10 doesn't eqal 7, so it isn't neutral. By elimination, I'm pretty sure it's an alkaline.

A

Because as stated before, Keq=10^-14=[H+][OH-]
OpenStudy (anonymous):
It can't be 10^7M. That'd give you a negative pH.
OpenStudy (anonymous):
Do you mind to help me on a little more? like 10?
OpenStudy (anonymous):
Sorry, I'm a little behind, and I need to catch up with school.
