Question
Which of the following accounts for the observation that the pH of pure water at 37°C is 6.8 ?
A.
At 37°C water is naturally acidic.
B.✓ Correct
At 37°C the autoionization constant for water, Kw, is larger than it is at 25°C.
C.
At 37°C water has a lower density than it does at 25°C; therefore, [H+] is greater.
D.
At 37°C water ionizes to a lesser extent than it does at 25°C.
