    Please no pictures I deficiency the counter-argument typed quenched, thank you.

    The Kw of soak varies with atmosphere. Consider the pH of soak at 46⁰C with a Kw = 1.219 x 10-14. Show total calculations ascititious to an counter-argument.

    Answer:

    first we should consider the H3O+  concentration.

    H2O + H2O ————–> H3O+  + OH–

    as we know

    [H3O+] [OH–] = Kw

    [H3O+] = [OH–]

    [H3O+]2  = Kw = 1.219 x 10-14

    [H3O+] = 1.10 x 10-7 M

    pH = – log [H3O+] = – log [1.1 x 10–7]

    pH = 6.96
