Kw = [H+][OH-] = 1.0 x 10-5
It is very important to know that neutral pH changes with temperature. The key part to this problem is that the solution is neutral! In a neutral solution the pH and pOH are equal and therefor so are their concentrations.  
 So, the value of [H+] = [OH-]. Lets assume this value is x.
So, x2 = 1.0 x 10-5
x = ?(1.0 x 10-5)
