Homework Help: Chemistry

Posted by Cliff on Monday, December 13, 2010 at 10:45pm.

I'm trying to solve some chemistry problems, like the ones my teacher says will appear on our exams.

The problem reads like this:

What is the hydrogen conentration in a bleach sample that register 9.55 using a pH meter?

My Attempt:
Since this sample register a 9.55 on a pH meter,it occurs to me that this sample is basic, and I can use the formula:
pOH = -log (H^+), to solve for (OH^-)
From here I thought,maybe if I substitute that result into the equation pH + pOH = 14, I might arrive at the answer I'm looking for; which is 0 000 000 000 35 M.

pH + 0.980 = 14
pH = 13.02
Evidently I took the wrong approach.
Can you help me with this problem?

Have a Great Night
