The value for Kw is 1.0 x 10-14 at 298K, but this value is temperature dependent. Given what you know about Kw and acid/base chemistry, what will the pH of water be at 283K if the value for Kw is 0.29 x 10-14? Is this solution acidic, basic, or neutral?
a. pH = 7.26, acidic
b. pH = 7.26, neutral
c. pH = 7.00, neutral
d. pH = 14.54, basic
e. pH = 7.26, basic
