Postby 905085650 » Sun Jan 20, 2019 3:58 pm

Can someone tell me the autoprotolysis equation and explain it to me? Thank you!!

The equation is 2H2O → H3O + + OH-. The significance is that shows that water is amphoteric (able to react as an acid and a base).

The autoprotolysis constant is Kw = [H3O+][OH-] = 1.0 x 10^-14 where the concentration of H3O+ and OH- are 1.0 x 10^-7

I also believe it is significant because when solving weak base/weak acid problems, you can convert from Ka to Kb using the Kw constant = [H3O+][OH-] = 1.0 x 10^-14
