Hello! I have a quick question about finding the pH and pOH, but at temperatures OTHER than 298K. If we know one of them, e.g. the second example in your video where we know the pOH, and we need to find the pH, how would we proceed if the temperature is not 298K and we cannot use the "pH + pOH = 14" rule? Or is this perhaps something that we don't need to know?
