Hey guys,
I have a quick question.
I signed up to take Organic over the summer trying to get in all the pre-reqs for a 2+4 Pharm-D program. I would really like to do well in this class and was wondering is there anything I should review or any good study habits or methods I can use to ace...
Thanks for the response.
Well Kw= [H3O] x [OH]
So I got the value for pOH from the equation pk = 14 = pOH + pH.
I then found the concentrations for H3O and OH by using the formulas for pH (pH = -log [H3O]) and pOH ( pOH= -log[OH]). I then plugged those values into the orginal equation and...
Problem:
The pH of pure water at 37°C is 6.80. Calculate Kw,
pOH, and [OH-] at this temperature.
Work:
pH: 6.8
pOH = 14 -6.8 = 7.2
[OH]: 10-7.2 = 6.3 x 10-8 M
Kw= [H3O] [OH] = 1.5 x 10-7 x 6.3 x 10-8 = 1x10-14
Real answer:
pH:6.8
pOH:6.8
[OH]: 1.6x10-7
Kw: 2.5 x 10-14
What...
