    So, 2 = p[H+] = - log10(0.01) and you are looking to dilute the solution to a pH of 5 or 5 = p[H+] = -log10(0.00001). You want to dilute the solution from 0.01M to 0.00001M to give it a pH of 5.

    It would depend on your starting volume. This simple equation can help you figure out how much volume you need to finish with. (Mcon) (Vcon) = (Mdil) (Vdil)
