A saturated solution of hydrogen sulfide (0,1 M concentration) dissociates into cation [H+] and anion [HS-], where [H+] = [HS-]. When this solution dissociates, the following equilibrium equation is established:

. Find [H+]. (If [H+] =

*x*, then [HHS] = 0.1 -

*x*.)

I found this problem in my algebra book and I'm not entirely sure how to do it. I've took chemistry before but it's been quite a while, so..

I was wondering if i can seek some assistance, please?

I've had already tried: x^2/0.1-x = 1.0 X 10^-7

To: x^2 = 1.0 X 10^-7/0.1-x

Then: x^2 = 0.1-x/1.0 X 10^7

I'm unsure what to do from there.
