Question

What would be the pH if the [H+] = 3.00 x 10-5 moles/liter?  Please explain how to find this?

anonymous · Answer

the pH would be the negative log of the [H+] 
so you would take 
-log (3.00 x 10 ^-5) 
and that would be your pH
so 4.523 would be your pH

the equation/ formula is pH = -log [H+]

Thanks so much!!  I have one more question about this if you have a second.  Do I find the log with my calculator?  And what are the steps for doing this on a calculator?

I only use logs in the calculator, mine has a log button so I press the negative button, then log and put in the [H+] 
Your calculator might not have a log button, mine is a graphing calculator

Ok, makes sense! My calculator does have a log button, it's a scientific calculator.  Thanks again! :)
