C.14.26
D. 14.5
E. 13.26
Answer: E
Why?
(1). At 50 oC, the autoionization constant for pure water, Kw, is 5.48 x 10-14. The H3O+ concentration in pure water at 50 oC is ____ x 10-7 M.
What is the relationship between pH, pOH, and Kw at that temperature? (Note: Select all that apply.) I don't understand the last question. Any explanation will help! Review Problem 16.060 At the temperature of the human body, 37 °C, the value of Kw is 2.5 x 10-14. Calculate (H+], [OH"), pH, and pOH of pure water at that temperature. [H+] = 1.6 x 10-7 M [OH-] = 1.6 x 103 m pH = 6.80 The number of significant digits is...
