great review. though wouldn't pure water at different temperatures still be neutral? at each temperature, despite differences in pH, the [H+] is still equal to the [OH-].
You are correct that water will still be neutral since the [H+] = [OH-] at all temperatures, but the Kw changes with temperature so what is considered "neutral" in terms of pH actually changes. Only at 25C is neutral (the definition of neutral is that the [H+] = [OH-]) equal to a pH of 7.00. At higher temperatures, the Kw changes and what is neutral in terms of pH actually changes and the pH is lower than 7. Your entire frame of reference changes with temperature since the Kw changes with temperature. This is why you will always find Ka, Kb, Ksp values at 25C in textbooks. Hope this explanation helped.

Bro clutched up ngl
Why didn’t we have someone like you 15 years ago? These Gen Zers get the best of everything lol 😅--Millennial
Thanks for watching - please share with others!
Isnt water even at high temperatures neutral? The new neutral goes from 7 to below 7 but the concentration of OH- = H+
