Acids, Bases, and Autoprotrolysis

[Connie Liang 3L]

Is my understanding correct that in acid/base reactions, autoprotolysis of water still happens because the overall acid/base reaction happens in water?

[Charlotte Adams 1A]

I believe that is correct because I know that for an acid/bas reaction Ka*Kb=Kw which is the constant for the autoprotrolysis of water

[Katherine_Douglas_1F]

Yes, I am pretty sure that is what is happening. Keep in mind that any body of water is undergoing autoprotrolysis at a very slow rate. That is why the disassociation constant (Kw) is such a small number (1.0 x 10^-14).

[Kaihan_Danesh_2J]

yes, the autoprotolysis of water occurs constantly, before and after any neutralization reaction and at the same rate, so you do not have to consider it in your calculations.

[Alexandra Salata 2L]

Yes, this is right.

Ka (acid disossication constant) * Kb (base dissociation constant) = Kw, which is for the constant for autoprotrolysis of water . (This is also equal to 1x10^-14)

[AndrewNguyen_2H]

Yes, water is always autoionizing at a small rate.

[Shreya Patel- 2D]

Does that mean autoprotolysis can only occur with water? What are some examples of it occurring outside of water?

[Brandon McClelland3L]

Yes, some autoprotolysis always occurs in water.
