We’re being asked todetermine the H3O+ concentrationif = 3.9 × 10–3 M. We’re givenKw = 2.5 × 10–14at 37.0 ˚C.

You are watching: What is the [h3o+] in pure water at body temperature?

Recall thatKwis theauto-ionization product the water. For the adhering to reaction:

2 H2O(l)⇌H3O+(aq) + OH–(aq)

the auto-ionization product constant is offered by:

*

Note that each concentration is elevated by the stoichiometric coefficient: and also are raised to 1.


*

At body temperature that 37.0°C, Kw = 2.5 x 10-14. Calculation the if the = 3.9 x 10-3 M.

A. 2.5 x 10-12 M

B. 6.4 x 10-12 M

C. 3.9 x 10-3 M

D. 1.0 x 10-7 M

E. 2.5 x 10-14 M
