******Medal in Exchange for Chemistry Help******

For a note taking assignment in Chem we have to answer these questions, but I don't understand how you do them. I would really appreciate your help in solving them.

What is the pH of 1 x 10^-11 [OH-]?
What is the pH of 3 x 10^-6 [OH-]?

do you just want the answers

anonymous · Answer

I would love the answers, but the explanation would be appreciated as well. I'm on a deadline to complete the assignment by 11:59 PM EST, so I'm trying to complete everything today. :) @clayton1012110

there's a logarithmic relationship between the concentration of H+ ions in a solution and its pH. Do you know what it is?

anonymous · Answer

No, I'm sorry. The best guess I have is K^w, but I have no idea what K and W represent. @JFraser

Use the formulas 

$\sf \large  pH+pOH=14$

$\sf \large pH=-log[H^+]$

$\sf \large pOH=-log[OH^-]$

Oh! Thanks! I knew the ph to POH formula but not the other one. This will definetly help. :)
