So you keep posting your homeworks here and have others solve it. You will go far, specially since you don't even thank the people who solve your problems for you (check your last thread). Am I right to be annoyed with these kind of postings?

Even though I am not a chemistry major and have taken only general chemsitry, these are the some of the easiest problem realted to pH. Sove it using the :Henderson–Hasselbalch equation. If you don't know that that is: http://en.wikipedia.org/wiki/H... pH is given, ka is given, calculate pka and slove for the ratio of base/acid.

i know the answer but don't wanna use my brain sorry

This is the easiest chemistry problem, just use HH equation 1.PH=Pka +log(B/A)  , B is the concentration of benzonate and A is the concentration of benzoic acid. 5.9=-logKa + Log(B/A) 5.9= 4.398  + log(B/A) logB/A=1.502 B/A = 31.768 2. PH=Pka +log(B/A) , B is the concentration of hexonate ion and A is the concentration of hexanoic acid 6.09  = 4.384 + log(B/A) Log (B/A) = 1.706 B/A = 50.815 make sure the calculation is right in case..
