Kw for acidic/basic solutions

Postby ShastaB4C » Mon Jan 13, 2020 1:48 pm

How does the temperature change of a neutralization reaction not have an effect on the K of the product solution? Or is it of the water?

Is the Kw for water always 10^-14 at any temperature or does it vary?

I think in the case of calculations we say the temperature increase from the neutralization reaction (from the formation of a O-H bond) is negligible and therefore, the K doesn't change

No, the Kw is not 10^-14 at all temperatures, just at 25 degrees C.
