pH+pOH = 14

[amreen_sandhu1k]

Can we only assume that pH + pOH = 14 for reactions involving water at 25 degrees C?

[Minh Nguyen 3H]

This equation/relationship always hold true for reactions in water at 25 degrees celsius, but can be different at other temperatures.

[eunicevazquez_2I]

Yes that us correct because it decreases as temp goes up

[Harshitha_Pandian_3F]

We know that this specifically always will hold true for reactions at 25 C but not the same for other temperatures. We usually are given a temperature and I think we assume it as at 25 C if we are not given one.

[Bobak Pourrahimi 2L]

Yes, this is confirmed to be true at 25 degrees celsius, but will vary at different temperatures.

[Mya_Chiarappa_2C]

Yes, this relationship can only be assumed at 25ºC because it changes with temperature.

[Cindy Vo 3E]

Yes, this is true, but only for 25 degrees Celsius! It changes for other temperatures, which is why he emphasizes that its at 25 degree Celsius in lectures.

[905767718]

Yes, however it's not an issue when thinking about it because all problems in the textbook problems and achieve questions are written with the implication that the temperature is set at 25 degrees Celsius.

[JennyZhu1K]

Yes it can only be assumed for standard conditions: 25 degrees Celcius and 1 ATM.

[Aashna Bhandari 1L]

Yes, we can say pH+pOH=14 under the standard conditions of 25ºC and 1 atm.
