Please help me figure out this problem, I just want to say thank u all for helping me with the others problems, I would be no where without you all, thank u thank u !

In chemistry, pH is based on a
logarithmic equation as pH = -log[H+]
where H+ is the number of positive
hydrogen ions. My horse is not
feeling well and I note that his positive
ion concentration in his urine is
6.35 * 10 ^-6. Calculate the pH number
and describe whether it is acidic or basic. Note: 7 is neutral, above 7 is basic
and below 7 is an acid.

Again, this is another "plug-n-chug" question...

$\text{pH}=-\log(6.35\times 10^{-6})=6-\log(6.35)$

What do you get when you plug it into the calculator? You should have the hang of this by now!

3. H+ = 6,35*10^-6
ph = -log(6,35*10^-6)
ph = --5.197226
ph = 5.197

Where I used my calculator to calculate log(6,35*10^-6) using the log key.
