Acids, Bases, and Autoprotrolysis

Postby Connie Liang 3L » Sun Jan 17, 2021 3:13 pm

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

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

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).

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.

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)

Yes, water is always autoionizing at a small rate.

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

Yes, some autoprotolysis always occurs in water.
