Homework Help: Chemistry Acid/bases

Posted by Spencer on Tuesday, February 10, 2009 at 8:11pm.

The concentration of H2SO4 in a solution is 3.20 10-6 M. Assume the acid dissociates completely in solution.
What is the [H3O+] in the solution?

What is the [OH-] in the solution?

What is the pH of the solution?

What is the pOH of the solution?

OK SO I KNOW HOW TO DO THESE TYPES OF PROBLEMS, BUT I CANT SEEM TO START IT I MEAN, I ASSUEMED THAT THE MOLARITY WOULD = THE H3O+ ION BUT THAT WAS WRONG. HOW CAN I START THIS TO GET THE FIRST PART, THEN I CAN SOLVE IT?

If the sulfuric acid COMPLETELY dissociates, then the hydrogen ion concentration is 2*M (there are two H in H2SO4).
