Autoprotolysis

Postby 305086803 » Sun Jan 19, 2020 11:22 pm

Could someone explain and describe the relevancy of autoprotolysis to the course?

Dr. Lavelle gave an example of autoprotolysis in class, which is 2H2O ---> H3O+ + OH-. This is one of the most common equilibrium reactions that shows the equilibrium constant and therefore the autoprotolysis constant Kw.

I believe Dr. Lavelle covered autoprotolysis as a way of explaining how 10^-14 = Kw = Ka * Kb, an equation crucial to calculating equilibrium constants and pH / pOH. Other than that, I don't think there's anything else important to know about autoprotolysis.

Oh okay this makes sense...thank you.

It's essentially describing how H2O is also being converted into H3O+ and OH-, but at extremely small concentrations compared to the much more stable concentration of H2O.

Okay thanks so much everyone!
