Question

find the pH and the pOH of the solution
1. 0.023 M solution of perchloric acid
2. 6.6 x 10^-6 M solution of nitric acid
3. 0.0334 M solution of potassium hydroxide

Answer 1

One sec.

Answer 2

For future reference, pH=-log[H+] pOH=-log[OH-]
Wait...crap...I might have messed up if those molarities are for the acids in general instead of the H concentrations...

Answer 3

Wait...I just messed up the order. Here. I'll fix it.
pH:
1.) 1.638
2.) 5.2
3.) 12.524
pOH
1.) 12.362
2.) 8.8
3.) 1.4763

Answer 4

so pOH is just 14- ph? and ph is -log (x)

Answer 5

Kinda. You need to user the mole ratio to find the concentration of H. The mole ratios were 1:1 though, so I could skip over that part.

Answer 6

Ex: H2SO4 2H/1H2SO4 ratio: 2-1

Answer 7

I think. Dx Sorry. Haven't done these in quite a while.

Answer 8

hey thanks for the help
