If the ph is 8.26, what is the hydrogen ion concentration?
and
calculate the ph of 0.0823 M H+?

for pH = 8.26
[H+] = 10 ^ (-pH)
[H+] = 10 ^ (-8.26) = 5.495 x10^(-9) = 0.000000005495 M
for [H+] = 0.0823 M
pH = -log[H+]
pH = -log[0.0823] = 1.0846

pH is defined as minus the base 10 log of the hydronium ion concentration. Therefore pH of 8.26 means 10 raised to -8.26.
Most scientific calculators will do this for you
When I crunch the number I get 5.49 x 10^ -9.
For the second part of your question, just take the base 10 log of 0.0823 and change the sign of the result.
The log of 0.0823 is -1.0846.....so the pH is 1.08
Just remember the definition....pH is minus the base ten log of the hydronium ion concentration.

pH is equal to -log(conc of H+ in M)
1. pH is 8.26 well i dont know
2.conc is 0.0823,pH = -log 0.0823 =1.084

Ph= - log [H+] , substitute the Ph then calculate the hydrogen ion conc.

Why didn't u ask this 4 or 5 yrs ago ??? then I was really a chemistry expert...but sorry for now...u know I have totally forgotten high school chemistry...
